Just recently got some rims shipped from Japan. The paint on the rims was peeling and oxidated. So I stripped the paint in attempt to restore the rims. After stripping the paint, I've found some build-ups that I was unable to remove with household chemical like Simple Green, Lime/Calcium removers, etc. Has anyone successful did this themselves and have an answer to remove it. I like how the rims are with the paint stripped, so I decided not to repaint them. Thanks.

Here are some pictures so you'll know what I'm talking about.

Before paint was stripped.


After paint was stripped.

 

Looks to me like aluminum oxidation. It happens on lots of aluminum OEM wheels that the paint/clear chips off of and when the brake dust eats at them.

If it is that, which it appears to be. Only sanding/buffing them will make that smooth again without the corroded spots.

 

It might be some epoxy primer that is has held on to the metal!! I used Aircraft stripper to get it off, and it may take a couple trys to get it ALL off!! GL

 

it just looks like you didnt strip off all the paint.....

 

All the paint are actually gone, those are just oxidation or whatever it is. I used Aircraft paint stripper, and actually did it 4-5 times while stripping the paint. I've even left it overnight to make sure the paint stripper penetrated throughly. Any other suggestions or solutions?? Thanks all!!

 

sandblasting might take all that off
