What to paint headers with?

Eastwood Silver Hi-Temp Coating
I just ordered some of this. Won’t get it on until later this winter so can’t say how well it works yet.

I used the Eastwood stuff years ago on a set of Hookers. Blasted and cleaned them, brushed on a coat and had a local powder coater bake them in his oven. Repeated a 2nd time. Surprised they lasted 5 years until I sprung for TTI's.
