Stripping old ceramic coated headers and recoating them with high temp vht 2000°

I have never heat cured header paint, not saying not to. I do believe that the surface prep is very important, and I do not lay on heavy coats, very light thin coats. Then they sit for a long time. I try and do them a month or more out before using them. Haven't had any peeling problems yet on headers or cast iron manifolds. Oh, and yes, silver header paint does work great on silver plastic grills and trim like for instance a steering wheel. I do coat that with a satin clear to protect it. Again, no heavy wet coats. Have fun taping.
