EMPI STOCK TAIL PIPE DRESS-UP - CHEESE GRATER Rusts Tail Pipes!
I got most of the rust off except for a few specs with Naval Jelly and by rubbing lightly with steel wool.
Then I polished them with Brasso brass, copper, and chromium polish.
Then I applied some McGuires wax/polish.
The Naval Jelly slightly tarnished and discolored the pipes a little, but now they look almost as good as new.
