That is the stuff, and I used it on my truck wheels first, and they came out looking brand new. So tried on my motor, really cleaned it up. Showed Josh at Gateway Cycles (was St. Louis Big Dog Dealer ship before Big Dog went out of business), who knows my bike as we talked about how to clean that part, he was really impressed with the turn out. He has some now. Used it on my Honda 1800 vtx wheels and they turned out looking new, and I have tried polishing them could never get them to look that good. They are not polished, as the chopper are, but the look like the just came of the showroom floor. That bike is 14 years old. Just try a small area a round oil filter, that way it easier to wash off without with out getting everything else wet. I am telling you it works you will be amassed. It did not dull any of my aluminum covers on the engine.
