Have you tried hi temp paint.....lots of guys have used BBQ grill paint with success.
Oh yeah, it works great but has not held up to rocks and stuff that the road throws at you. They still look great from about 5 feet (after 4 months) but I can see them needing a new coat in a few more months. I have not used the BBQ paint, used stuff designed for headers instead. Maybe on the next paint job I'll give the BBQ stuff a shot, thanks for the tip.
