I have a Brinkmann Smoke-N-Pit Deluxe (without fire box) that has served me very well over the last 11 years. but since moving to the east coast 2 years ago rust has really taken ahold of it. I just received a Brinkmann Dual Zone Charcoal/Gas Grill Model# 810-3821-S as a gift from a friend and am setting about "restoring" the smoke-n-pit as a dedicated smoker. I am thinking to use high temp header paint on it after sanding all the rust down. Any suggestions?
