Does anyone know if powdercoating can be removed? I got a set of wheels from MikeZ and want to change color. Red just doesnt go with any color I want to paint my car. Can they be stripped and brought back to original? The silver or grey would go nicely with just about any color I go with.

Just use paint remover from Home Depot, etc. Works good, no scratches.

the last time I dealt with powdercoated engine tins, it had to be bead blast with red oxide which last a bit longer than glass bead. it does not come off easily unless the powdercoat job was done poorly.

i don't think paint remover could do the job.....i might be wrong but I know i've tried pretty much everything else but the blast to get the coat off ....very hard until i used the red oxide media, aahh a bit better....

I am at work right now till around midnight, I will try it tomorrow on the back side of one of the wheels and see if the paint stripper will take it off. If not, I may just do as Mike suggests and just rattle can them with some silver. Maybe I will use that ceramic type paint, it seems to hold up pretty well and it looks nice.

I asked that too and Mike said he didnt think it would stick to it without stripping off the old first. Which makes sense when you consider it has to bond to the metal magnetically.

Why not try wiping one wheel down with acetone and painting it to your liking?

Maybe hit it with 0000 steel wool. (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

How about a pic of those wheels?

BTW , you can get a "no sand" paint prep for painting over paint. That might be worth a try.

You can powdercoat over powdercoat, but it doesnt turn out as nice.

One could heat the part prior to spraying the powder (which melts it as it is applied).

One way to "strip" the parts would be heat. They could be burned off (potentially hazardous to wheels). Other than that, bead or sand blasting would probably be the way to go.

If you are going to re-powder coat the wheels, the pits created while blasting will be filled in and smoothed out as the powder flows out during the curing process (oven).

I don't think any paint will stick well to powder coated parts.

just my $0.02

please, no pictures until they are freshly painted...I don't think I can stand seeing those "hooker-lipstick-red" wheels anymore (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

I'd try scuffing the coating and paint or the chemical strip..it's not going to be easy or quick

Yes you can. I had a CBR600 Honda I took apart and had the frame powder coated in blue then a clear powder coat over that it came out sweet.

Paint remover works (the good stuff). I remove that crap from anything I ever get that has powder coating on it. Powder coating sucks! At least where I live, powder coating is a death warrant for the part that's been coated. It's guaranteed to corrode the part. Around here paint will protect the part 10 times better.
