I could use some advice. I was washing my bike and there was a mark on the exhaust. Probably a mark from a shoe (or maybe a saddlebag) touching it when it was hot. I had two scrubbers I was using...one was plastic like which I was using for scrubbing bugs, etc and the other was a kitchen type scrubber. Long story short I used the wrong one and scratched the exhaust. Now I am looking for any advice on polishing it back up. They are fine scratches...like the chrome looks kinda dull in the spot I was scrubbing. Any products/method I could use to get the shine back?
