The paint was just rustoleum Ford Blue high heat engine enamel, so nothing too special, just the good 'ole rattle can. I did use a primer with it thats specifically for plastics, but I don't remember the brand. I think the finish came out the way it did b/c of the plastic itself, not sure tho.
Anyway, i saw the Boss 302 covers (that look pretty much the same) going for ~$100, so I'm proud of my $10 paint job
