Haven't yet. I've been thinking about trying ceracoat. Don't know if the other products are related but ceracoat is ceramic based and is suposed to be outstanding on guns. I believe the bake temp/time for ceracoat is very close to what I typically use to temper 1084/1095. I'm thinking I can do one temper cycle, bead blast, spray with ceracoat, and then back in the oven for a second cycle/finish cure. Let us know how it works out if you try it.
