I thought I read somewhere (I wish i could find it) that polishing an exterior metal surface would help keep heat inside (assuming the heat source is inside already).
Would there be any advantage to polishing/buffing the exhaust pipe (is it called a header?) other than making it shiny?
Could anything bad happen?
