What do you "clear coat" with?
Funny you should ask. I'm still "playing" around with a few things in the rattle-can category. First I tried clear acrylic, and that was the worst thing I've ever done. Dries hard and fast, which is the first clue it's no good, and then it cracks after about a year, so you have to re-do it. I tried some enamel-type clear that I found at a hobby shop. Stuff yellowed. Lastly, I've been using the polyurethane clear "wheel paint" by Duplicolor. That stuff is like spraying water, and it goes on so quick, that before you know it, you have a run. It holds up well, doesn't yellow (yet) and so-far-so-good. Only problem I've noticed after I sprayed the brake calipers......it's not brake fluid proof. But then, what is?
Maybe there's an epoxy based clear out there somewhere
