Hello,

I bought a pair of wheels for track use that had pretty ugly paint. My other wheels are stripped and buffed. Paint stripper took off the top layers, but hasn't done much for the powder coating. Anyone have experience stripping the rest?

I've read some conflicting stories about various chemicals like aircraft stripper, but I'm looking for people with experience doing this.

Thanks,

Jon

You might need to have them sand blasted. That's the only way I know of to remove powder coating.

Blasting won't do a good job on the wheels, especially the factory paint layer. I have had several sets powdercoated and the local guy we use sends them to a chemical stripper. They get dipped and cleaned. Leaves a smooth and clean surface for the new PC.

Okay. I've never had wheels done. Just the gate across my driveway. I guess it was too big to dip.

Any idea what chemical is used? Large metal coatings company here that does all types of electrostatic (powder) finishes told me they only thing they know of is burning it off in a high temp oven. This can adversly affect the heat treating and strength of certain metals.

I get asked often about the PC removal as I've been using the process since the mid '80s.

Thanks

When I used chemical dip on my wheels (my previous car) I ended up with lots of little pits (0.3mm deep) on the wheels from where the brake dust settled - some chemical reaction which ate away into my wheels. It was a disaster.

PowderCoat

Contact Kolene Corporation and ask them about their Recover Product. It will take the powder coat off easily. Talk to Tom Strickland

Well done. Thanks for posting.

OK, I have the wheels stripped now. I called Kolene, as PowderCoat suggested. They do a chemical dip at 300 F, and I would have had to ship the wheels to and from Detroit. Didn't like that option.

I found a place closer to home that uses a plastic bead blast. $40/wheel. The results were quite satisfactory - see photo below. I would like them buffed out, which will take some hand work, but they are definitely ready to be painted as they are if anyone wanted to do that. I'd certainly recommend this approach.

Hey I know this is old thread but I have some turbo twists that are black and want to return to stock color

How did this hold up over time?
Would you recommend the bead blast?
When blasted is it back to stock color and I could just do a clear powder coat or do I need to pick a silver one?

What city was your vendor in out of curiosity?
Thanks

I'm doing the same thing at the moment, my local powdercoater did not reccomend sand blasting, they said they will chemically strip them.
As far as the colour goes they were not able to match the metallic silver porsche colour but found a silver that looks exactly the same and will require a clear coat to make them shine. I'm getting mine done next week.

Cool! Let me know how it goes. You're not in the SF Bay Area by chance? if you are, let me know where you're getting it done!

Dingo

Will do, I actually made a few further calls today and found a place that refinishes wheels by spraying them and can colour match for roughly the same price so I'll be going down that route now.

Get a garbage bag, get some industrial paint stripper, use a chip brush to brush on the paint stripper on the wheel cover with garbage bag.
Clean it off, scrape/sand or repeat stripping process.
get excess stripper off with degreaser or ISP 95%
Clean with Trisodium phosphate and HOT water, distilled if you can.
Fill rashes with body filler or epoxy.
Sand with 100.
Tack everything up with tack cloth.
Follow directions on can with product below, FOLLOW THE DIRECTIONS CAREFULLY, esp the flash time and don't rush.
2 coats of primer need 2 Coats of silver paint and 2-3 coats of gloss lacquer.
If you do this slowly and correctly you wont have to correct with sand paper and polishing.

Make sure you're inside with low humidity with garage door cracked.
WEAR PPE (P100 RESPIRATOR, NOT MASK IS A MUST) Full mask if you can, this is some nasty, nasty stuff.
Wear gloves, this stuff is nasty, Cleans with gasoline.
