Another point to consider and check up on, is that lots of platers won't touch a used exhaust system as a tiny amount of carbon can mess up a whole tank of fluid. My own plater won't even accept a used petrol tank.

As far as exhaust paint is concerned. I use this on second hand exhausts, like this on my WD/G which has covered probably 2000 miles since I sprayed it. The only draw back is they only sell the rattle cans in boxes of six. Ron
