Does anyone have any experience with surface coatings for the INside of a fin can to protect it from exhaust gases? I'm thinking of trying some of that paint for the exterior of barbecues, but it says not to use it for areas that are going to be exposed directly to the flames. The exhaust nozzles are nearly in direct contact with the body tube, and are recessed about 1 1/2 inches into the back of the rocket, so 24mm F-72's are going to burn through my fin can if I'm not careful.
