I used it. Had an old set of headers blasted and then used their primer and paint. It was on the 72 that only sees track time but it held up ok for a while. Then it started to show rust through the paint. Pretty much like any other paint I've tried.

I would think el cheepo BBQ paint would work as good.

That said, member PROSPORT has his headers painted W/ an Eastwood Co high heat silver and he's been real happy with how they've held up.
