Just wondering if there is any type of finishing that is used on the inside of these steel smokers. Obviously, a lot of people paint the outside with a high temp paint, but is it best to leave all the interior steel completely as bare metal?? Is rust an issue? Most commercial made smokers and BBQ's have some sort of enamel finish on the inside unless they are stainless. I am mostly concerned about would to do with my RF baffle plate. It is made of 3/16" steel and i am wondering if i should paint it with High Temp or just leave as is???
