Very high temp paint???

On a buddy's headers; Read the directions, hung them up and sprayed. THEN, got a big weed killing torch that would smoke anything you own, used a digital therm, heated headers to proper temp, per instructions, cool, heat, cool ,heat, etc (different temps). Installed the engine, then gator wrestled the headers in- (a lot of banging and scraping), no scratches. We stood there in awe; something we read actually worked.
