Cooked 2 pizza's last night at 700 degrees. SS near the kettle did not get affected at all. If it works out I may put on true car wrap. I like the stainless but when the sun hits it I burn out my retinas. Also want to protect the stainless for the future. I wonder if true car wrap would work on the plastic tops. May have to drive to Maine to get the performer for 50 bucks to try it.
