Painting a SS muzzle device?

I’ve got a SS BattleComp that I need to paint black for work. Any advice on what’ll stick? I’ve used Krylon and such to paint stocks and barrels, but I don’t know that it’d stand up to the heat and blast. Any recommendations…high temp paint?

Black high temp grill paint. 5 bucks at Lowes.

I used old black can I found in garage. It is still on it two years and few thousand rounds later.

OK good. I’ll rattle can it tomorrow.
