What Is Powder Coating? New Wheels For The S2000!
What Is Powder Coating? New Wheels For The S2000!

Hello, everyone and welcome! In this video we’re going to be learning all about powder coating. Now the only reason this video is possible is because incredibly a subscriber by the name of Erin Gallinger who happens to run a wheel repair and powder coating shop, noticed that my S2000 wheels were in pretty poor shape and had a set of AP1 wheels in his shop that he was willing to refinish for me so the S2000 would be looking clean. So a huge thank you to Aaron of phoenixrimrepair.com you can follow his work on his instagram handle @expressphoenix which I will of course include links to in the video description. Moving on to powder coating, this is a type of coating that uses a dry powder to apply a finish to a product whether that be a household appliance, car parts, or in this case AP1 S2000 wheels. Powder coatings tend to be tough hard and durable, which is why they’re commonly seen in automotive applications. So let’s walk through the process and learn about how this all works to start off the wheels go into an acid bath to strip any paint or clear coat off of the wheels. They need to be completely cleaned before the powder can be applied. With the wheels cleaned they are now prepped so that the surface is nice and smooth essentially grinding off any damage that’s on the wheels so they have a uniform smooth finish and look good any imperfections are removed so that once the wheels are coated they look as good as possible. An angle grinder is used to clean up any major damage and then a finer finishing sander is used to smooth out any of the larger scratches left behind from the angle grinder this is also used to soften any sharp edges for a more even powder coating the powder will sometimes pile up on sharp edges, due to the electrostatic field and sometimes it won’t properly flow out to cover the sharp edge. After all four wheels are smooth we move on to sandblasting. Sandblasting starts with the back of the wheel cleaning the hub area free of any debris, rust, whatever has accumulated on it over the years. Then moving out on to the spokes making sure you can see the part numbers and removing any road grime, then moving on to the outside edge of the wheel. Sandblasting is done to clean the wheel and it also roughens the surface a bit which allows for a nice bond with the powder coat and now we’re ready to get started on the powder coat so the final step before applying the powder is to spray the entire wheel down with compressed air and make sure the surface is completely cleaned off, no remaining sand left on the wheel or trapped in any of the grooves. This is where the cool stuff begins starting with the powder. The powder is a blend of polymers, pigments, and other ingredients which are mixed in a hopper. The hopper has a fluidizing plate at the bottom which flows air up through the powder keeping it in a liquid like state for application. Aaron is using his own self-made fluidizing hopper. Now looking at the powder coating gun on the front of it is a corona ring which is attached to ground and this captures any overcharged powder particles, so they don’t cause any disruptions on the wheel. Not every powder coating gun has a corona ring on the front of the gun you can see the X pattern tip for spraying powder which Aaron says he prefers as this allows for easier application into the faraday cage areas presented in the complexities of alloy wheels once removed you can see the electrode which charges the powder and then a white plastic sleeve around it which protects the powder gun from getting any cured powder inside of it this electrode tip operates up to 80,000 volts this high-voltage ionizes the air surrounding it meaning the surrounding air particles don’t have a matching number of protons and electrons in other words it creates a cloud or field around it with a charge there are different guns available some with the ability to provide negatively charged particles and some provide positively charged particles with Aaron’s powder gun the powder is forced through the ionized field using air pressure and then the powder picks up a positive charge as it passes through the wheel in this scenario is grounded as the charged powder particle moves through the air they head to the nearest ground which in this case is the wheel which the powder then sticks to Aaron mentioned that his equipment is somewhat antiquated in this video and that he uses a higher quality and much newer gun for clear powder top coats and glossy coatings but for my AP1 wheels being satin finish the older equipment is perfect for show quality results. Now the rod that you see the wheel is hanging from his copper, and this copper rod is connected to a ground rod. Which is solid metal coated in copper pounded eight feet down into the ground to ensure that the powder coat has a good ground to attract to essentially the gun sprays out charged powder particles the wheel acts as our ground and the powder sticks to the ground so he starts at the back of the wheel works his way around gets the side of the wheels going nice and slow and making the powder gets onto the wheel. The pressure the powder comes out is only about 2 to 5 PSI, so you’re really just allowing the powder to flow out and then letting that charge force the attachment with the wheel. Aaron then removes powder from the hub area and center bore so that the wheel fits on the car fine without any tolerance or clearance issues this also makes sure that the hub can sit flush if you leave powder on the back of the hub it can cure in a non uniform surface, so when you go to balance the wheels it won’t be as accurate as it should be and it can also create a safety Hazard where if you don’t remove that powder from the back of the hub if that cured powder flakes or falls off you now have a gap between your hub and the wheel meaning your lug nuts may no longer be tight enough and now you’ve got bigger problems where you have to worry about your wheel falling off in other words an important step not to skip. And the final step the wheels sit inside of an oven and cure for 10 minutes after the wheels have all reached 400 degrees Fahrenheit now this is where the conspiracy theories start to run wild on the internet about whether or not this curing process weakens the wheels in any way so I asked Aaron for his opinion on the subject he mentioned that while he has seen cases of straightening wheels and using heat to do it can cause wheels to be weakened he hasn’t noticed harm from the powder coat process. The process he uses is actually in line with other wheel makers and OEMs who have powder coat processes for example HRE wheels bake their wheels around 360 degrees while Prime wheel also has powder coatings which cure for 10 minutes at 400 degrees exactly like Aaron’s process. It also comes down to the initial quality of the wheel used as poorly cast aluminum wheels could be susceptible to weakening from the curing process versus much more robust higher quality wheels such as the OEM Enkei’s on the S2000. So hopefully this has been insightful, i’m super excited to get my tires swapped and get the new wheels on to the S2000 be sure to check out expressphoenix on Instagram and the links in the video description and of course a massive thank you to Aaron for hooking me up with these beautiful wheels.

    i have satin enkei wheels on my bike. Powder coating rocks!.

  6. Damien Koh says:

    Recent technology there is auto start/stop function. Most of people says it's fuel saving while heavy traffic but will it damage the engine and Will it degrade the pickup performance?

  7. DJLOUIE1000 says:

    Out of curiosity, why didn't you go for some 17" wheels? I heard they are a good upgrade for our AP1s.

  8. turbaN says:

    Oh boy do they look neat 👌🏻

  9. Peter Konrad Konneker says:

    Daaaaaaang. Dude does nice work.

  10. WhaoIfeelgood says:

    So do people do this to repair wheels or to make them look good orrrr ?

  11. SolamenteVees says:

    I don't usually like black wheels, but those look terrific.

  12. Jennifer WhiteWolf says:

    As you are in Portland, you should take a visit to Skips Wheel Werkes in Beaverton. He can show you wheel straightening, refinishing, and the best mounting/balancing in the region. Of course I am biased, I have known Skip for years, and our company now does custom glass beading for him. Your viewers would enjoy a tour of his small place with true old world craftsmanship restoring Porsche, Lambo, Ferrari, Alfa, and other vintage and exotics… Nice people, great work..

  13. Seth Kaplan says:

    Maybe an oversimplification but sort of like how laser printers work?

  14. s2syed says:

    Can powercoating be done with a high gloss finish, as opposed to this satin / matte like appearance?

  15. Powder Coating Institute says:

    Glad to see you doing a powder coating explainer video! We love the technology too 🙂

  16. Montrose Deloofs says:

    2JZ swap or I'm unsubbing

  17. GBRsolomon says:

    I'm glad you opted for black wheels – looks much better than the stock silver ones! I had the exact same colour combo on my S2000 and loads of random people used to comment on how good it looked 🙂

  18. Kid Refugee says:

    Very cool and a proper investment for a car like that. I've painted allot of wheels but always wanted to get set of wheels powder coated. I hear it's more chip resistant and for someone like me, who prefers longevity, it may be the way to go.

  19. idratherbeanonymous says:

    Wheels look great. Kudos Aaron.

  20. Rhubarb Pie says:

    FYI: PLEASE do not ever do abrasive media blasting with actual sand. The small silica particles can get stuck in the tissue in your lungs and cause silicosis over long periods. Most often, 120 grit aluminum oxide is used instead.

  21. v8power gaming says:

    I used to work next to that shop for a long time and never stopped by lol

  22. Integrafreak1 says:

    5:05 aaand also warped rotors

  23. Derick Martin says:

    How much he charge to do that?

  24. Jon Wen says:

    No pictures of them mounted on the car, I feel cheated…

  25. XoXKyleXXX says:

    bs.. to much work for some black wheels.. average person wouldn't even know the difference between that or regular flat black paint finish

  26. David Kent says:

    Video idea: explain differences in performance between 17-19 inch rims on different types of cars. Maybe even go as in depth as width of rim, size of tire, etc.

  27. bewbmike says:

    Love my black powder coated wheels on my spa yellow s2k. I kept the chrome lugs and silver centercaps though

  28. Lrn Fzx - Learn Physics says:

    "Creating a positive charge" – NO – you're just stripping off electrons. This misconception of "creating charge" really gets in the way of my students understanding chemistry and atoms and molecules.

    nice vid, fantastic wheels, enjoy.

  32. MadNotAngry says:

    Your boy Aaron is a douche. When he can't take a step without wheezing when he's 45, he can recall how badassed he looked working without a respirator.

    EE you dropped the ball on this video. Folks expect you to have a triple digit IQ.

  33. Yvonne M Feltman says:

    Those wheels are the best I've seen. What amazing skill! I'd like to hire that guy to do mine! And he ships!!!

  34. KingPNW says:

    There must be some mistake. I came here looking for a paid GMC promotion and found all this free content.

  35. Shorpy says:

    Looks really good.

  36. Arti Bacardi says:

    Oh, wow, those are nice! 👍👍

    S2000, what a weenie automobile

  38. Neil Amalfitano says:

    Explain wheel offset

  39. 10Bananas OFFICIAL says:

    It's perfectly fine to bake your wheels at high temperatures. I bake mine in the oven known as "Arizona" every day

  40. Remi Ramos says:

    They look amazing! Great job.

  41. martinez221704 says:

    They look amazing, will be stopping by his shop to get a quote.

  42. Derek Derkacs says:

    Those are going to look great on your car.

  43. Just for youtube says:

    Sick respiratory protection bro!

  44. ND96RAM says:

    It's worth nothing that after chemically stripping and sand blasting it's a good idea to treat the now bare portions of aluminum with a selective anodize (Alodine for example). Since the Al-oxide layer is gone you've greatly increased the chance of galvanic corrosion, and corrosion in general, at the wheel/rotor interface.

  45. C1osure says:

    If you do not powder coat the hub area on a steel rim it will begin to rust very quickly. So what's the answer for that?

  46. Jason T says:

    Interesting video thanks for posting!

  47. tiny b says:

    Nice respirator. Enjoy your plastic coated lungs.

  48. Nick Amarit says:

    Great color choice for the wheel and wheelcap logo.

  49. Richard Getz says:

    why do you need to acid wash if you are going to sandblast later?

  51. chris dyson says:

    Try not to drive these ones into your shelves 🙂

  52. Michael Walker says:

    One thing to watch for when getting stuff powder coatrd is WHAT powder they use. Epoxy is the bottom of the ladder, polyester is at the top. You can also get a mix of the two. Epoxy wasn't UV stable when I was powder coating and would fade over time. Some cars with black plastic trim parts do the same (start to go grey) if the supplier hasn't used UV stable plastic.

  53. RonJohn63 says:

    Who else read that as "New Wheels For $2000"?

  54. Rooshabh Nadkar says:

    Is powder coating for motorcycle wheels worth it ?

  55. Springwood Slasher says:

    Its when you coat something in powder.

  56. Luke Worden says:

    +EngineeringExplained, have you swapped your tires? Can't wait to see your S2000 with the new wheels!

  57. Strycnine says:

    Wow! Those look realllllly nice.

  58. Sei Parade says:

    What about powder coating the entire car? :3

  59. TerrificFlow says:

    I would have loved to learn the benefits of powder coating. Is it more resistant to scratches? Does it make the wheel easier to clean with high dusting brakes for example? Is it cheaper than traditional paint? Can it be applied to the body of a car? Can it be done on a whole car?

  60. Alec Dacyczyn says:

    I'm surprised he doesn't wear a dust mask for that.

  61. Kato x says:

    That you for this! You're about the only on on youtube that explained this.

  62. Yang Gao says:

    OEM wheels are made with way more process and controls, the raw aluminum wheel have to go through 16 stages of pretreatment in different solutions and powder coated once, bake for 30 min, spray paint and bake again, finally one more layer of clear powder and bake again.
    OEM wheels may not look as good as aftermarket wheels, but the quality standard is extremely high! There is no possibility that this shop spray and baked wheel will last through 30 hours of salt water and acid splash, which is a test for all OEM wheels!

  63. demskies says:

    I had my bmw rims powder coated black and was so excited to put them on, I even got new tpms,valve stems and tires. This was pretty expensive. Eventually I had a nail in my tire and needed a patch so I took it to a reputable tire shop and noticed the fix left a chunk of paint missing from my rims but not only that a few months back I curbed a sidewalk and no rash just another circular chunk missing….

    Is that normal? That doesn't sound very durable to me…

    I had the coated at wheel techniques in Santa Clara ca.
    I didn't read their reviews till after I dropped my rims off….take a look at the reviews, wow

    Did they have a clear coat after being baked ?

  76. Casey's Garage says:

    Powder coating is the way to go! It definitely transformed my old wheels

  77. Rickard A says:

    Sorry kid but you just ruined the age hardening of the forged Wheels from 6061-T6 to T something else that is brittle. Wheels are age hardened at 350 degrees and that powdercoater just baked them at 400+… Go figure..

    Hello! You have described the corona-gun nicely but up to my knowledge the particles leaving a corona-gun are negatively charged. Best wishes 1LF15

  85. Shailesh KS says:

    Yeah bro!
    You had to mention that the wheels are made by metal and metals are electronegative, so a gun which produces positive powder coat is essential in this case.

  86. Computer Services says:

    Problem with wheels that lived in salty conditions. Here they put salt on the road. Applying powder to salt damaged wheels causes air bubbles in curing process. Wheels look pretty bad up close.

  87. Gary Button says:

    great information! However, it should be noted that this is an expensive process and pending on a verity of factors, it may be cheaper to simply buy new wheels, In addition, it should also be noted that once damaged or scratched, power coated products are hard and expensive to repair.

  88. LoC says:

    They look really nice.

  89. Archibal BM says:

    electro deposition in air…

  90. da Bob says:

    Awesome, but sure would love to have seen them mounted!

  91. Jose J. Eduardo says:

    Price range??

  92. BajaDeezNutz says:

    Soooo… does the baking actually weaken the rims or nah?

  93. s2k442 says:

    Where did you get the center caps?

  94. WolfHeart says:

    Cool I didnt know there's electricity involved in this

  95. bruno burtoni says:

    So obviously u need a shitload of cash.

  96. Shaikh Shaan says:

    I really need to know about Eco friendly car paints and it's process

  97. Lokesh Anudeep says:

    Is single coating is enough for this process?

  98. Red Squirrel says:

    That's interesting, reminds me kinda of how a laserjet printer works.

  99. Mitchell James Gower says:

    Great informational video mate, I love it when I'm researching something and come across your video's. Looking foward to plenty more lessons in future. SUBBED 💙
