I've got mild/moderation oxidation on my E30 aluminum trim and have had a heck of a time trying to figure out how to remove it, or if it's even possible. I know the trim is clear coated, but I'm not sure if it's anodized. I've been told at Autogeek that if it's anodized there's not much that can be done. Does the clear coat have to be sanded off and recoated (as with the BavAuto.com product/Classic TrimCoat product)? I've heard mixed reports about the success of this approach. Or will a fine polish or paint cleaner work? Has anyone had success with this problem on an E30?
