I'm trying something on my engine parts while I've got the heads to my 5.0 off. I want to paint some of my engine parts in colors you can't get in high heat versions, most notably some of the dupli-color metallics. I first put down a few coats of dupli-color's High Heat primer. On that, I'm putting standard paint. Over everything, I'm putting dupli-color's High Heat clear coat. This is an experiment on stock parts, to see if sandwiching standard paints between high heat paint will protect the standard stuff.
I'm wondering how long this stuff might last. If it's gonna peel, anyone have any guesses when? Right away, a week, a month? I'll post back with my results, either way.
