r/Powdercoating

Hey y’all, I wanted to see if anyone has ran into their wheels leaking from the valve stem seals after powder coating?

TLDR: wheels were recoated 3 times due to coating issues, now all 4 wheels leak from the valve stem seals and goes flat within a few hours

To give some background, I had my 24 Civic Type R wheels powder coated in hyper silver about a month and a half ago. Had the wheels for about a week and the coating started melting off after the first wash. Used a non acid cleaner and it ruined the coating. Took them back to the coater and they redid the wheels again. Got them back and the wheels were totally flat AND the coating was 2 different colors on the wheels. I mentioned the tires being flat to the coater. After waiting a week I had them take them back a 3rd time to redo them again. After waiting about another week and a half (month and a half at this point) I got the wheels back. They look pretty good despite a few small imperfections but at this point I wasn’t going to nitpick them, I just wanted my car back. Got the wheels on the car and again, the tires had 5 psi in them. Filled them and they seemed to be fine. The next morning I took the car out and made it 4 miles down the road before my front drive went totally flat and my passenger was super low. Had to limp the car to my local gas station to make it home. At this point I’m tired of this coater and don’t want to deal with them anymore. I found the leak is coming from the valve stems on all 4 wheels. My question is do yall think it’s possible that they just left my stems loose or maybe the o-ring is messed up or the coating is uneven causing it to not seal.

I don't know a lick about powder coating. Could you do that on site? Our stairs are already installed and I'm guessing they planned on painting them vs powder coating. If this can be done on site is there a range in cost I should expect? Thanks!

I’m planning on powdercoating my Eride pro frame and swing arm the shop said I should buy about 4kg of powder but I think that’s too much how much would I need too powdercoat the frame and swing arm?

Hi all, *thanks in advance for any input.

I have been tasked by my employer to find a solution to removing the powder coating from these silicone masking plugs. Ideally of course it should be minimal labor involved.

So far I have tried to tumble them with media in a rock tumbler/vibratory de-burring machine.

I'm kind of thinking now to go the solvent/stripper method.

*If at all possible, I would like it to not be a generator of hazardous waste. Also, it should be something with minimal health risks, so minimal PPE requirements/no strong odors etc.

The idea is to "set it and forget it".

Much thanks!

My work refuses to listen to me about scheduled maintenance and lets stuff like this go until it becomes a problem. Every time we pull a rack into the oven, powder goes flying everywhere because of the bumps. It’s probably 1/4 of an inch thick in some spots. The guys and I have tried scraping and peeling it but getting it to budge enough to start peeling is harder than breaking up concrete with a sledgehammer. Also, if you guys have any recommendations on wheels and bearings for the racks it would be greatly appreciated, the kind we use now last about 3 months before completely disintegrating.

Long story short: local shop sorta fucked me. I need someone to coat one 13" wheel. I'm located in eugene oregon but travel up and down I5 for work so I could come to you. I'll provide the powder. Willing to pay a reasonable price.

Short story long: there's a shop locally I've used several times and they've done good work at a fair price. I recently brought them 2 wheels to coat along with 2lbs of powder which should have been more than enough. When I dropped them off the guy told me the machine usually needs a minimum of 5lbs of powder to work. This was strange as they had done a small caliper for me previously and I brought them a half pound of powder and they didn't mention a thing. He said he can try and make it work. Fast forward a few days and I pick up the wheels. When I get home I notice there's a decent sized blemish on the front wheel. My mistake for not seeing it when I picked them up. I sent a picture to the owner and he called me immediately to say drop the wheel back off to have it redone. I asked him if there was enough powder to redo the wheel and he said yes. I drop it off and get a call the next day saying I need to bring 2lbs of powder. I ask what happened to the left overs and was told they're aren't any. I say they either need to buy the powder and fix their mistake or I'll come pick up the wheel and asked for half my money back. The owner is clearly annoyed but agrees to half my money back. I go to pick up the wheel and they've not only sanded off the blemished part but lightly took a sander to the whole wheel to make it look like total shit. The other powdercoating shops in the area have $200 minimums. Can anyone coat this for me if I provide the powder? Willing to pay a reasonable price.

Thanks for hearing my rant

I’m going to powder coat my wheels and I’m wanting something that resembles copper plating.

Has anyone used fireside copper from prismatic powders?I’ve seen photos online and have a color swatch.

Looking for opinions/examples to see if there are any other powders that would match copper plating better.

I finally found the perfect color match to Dunn Edwards Cocoa at Prismatic, but the Prismatic powder is a matte finish and we need for it to be glossy. What can be applied to a matte powder in order for the finish to look glossy? The powder will be applied to regular carbon steel for a residential gate.

Hello, I have a question about the photo. I coated this frame with three layers: primer color and clear coat. Why is it peeling off these corners? After spraying, the corners had good coverage.
Thanks in advance!
