On a bike it might do ya OK, it is (IIRC) a very fine rubbing (if not actually a polishing) compound. The problem Ive seen way more than once around here on cars (ie; larger surfaces) is that you just cant be sure how much paint oxidation you have gone through, or even know how thick it was to begin with. The result, if not right away, is that eventually you start to see the thin spots where you went through too much colorcoat.
SO...beware, its a snakepit out there!
