Billet by Mothers is Far and Away the finest product I have ever used to polish metal in my life!! This stuff will make your radiator look like a piece of chrome in 20 minutes! I have used it on almost every piece of non chrome metal on the bike eg brake calipers, axle adjustment end caps etc and it blew my feeble little mind!! Previously I used the flitz system both paste and liquid, the mothers regular polish and several others including the old fashion stick polish with a high speed polishing wheel and nothing compares! Give it a try—it made my day! It is a little expensive but with respect to making the bike look good it is the best money I have ever spent.
