I have an Emit vapor shotgun with a Patriot V2 on it that are both brushed stainless steel. I'm thinking of buying some stainless steel blackener gel, by caswell, to blacken this setup. Any thoughts on whether this could work? It's just that i don't know if this will turn out right/it will be safe (it's a chemical, and the rda will obviously be subjected to heat, possibly causing some undesired reaction). Any tips, thoughts, and warnings would be welcomed with open arms.
