well... he is ending with a low grit because he is buffing on a wheel with good compounds and such great method but for several years i just went from about 120 - 280 mabey a couple inbetween up to 1400 if it was something that i really liked I'd taker up to 2000 and polish it out by hand, if you'v got a pretty smooth case mabey even take the paint of with a S.O.S pad and some elbow grease rather than ruffin it up so much with the sand paper.... any way pretty much you can just go higher grits till its smooth and polish it up if its not good enuf polish again or go with some finer stuff.. just keep the strait pattern "go with the grain if ya get me" and start with just the circle that sais yamaha, the case can be pretty tricky in the corners you may just like polishing that circle in the middle it gives a nice touch and is a bit easier for starting out.. if you feel you can do rest then mabey go for it... i just did one too where I polished that circle left the yamaha and the ring around the outside black and did the rest blue to match the bike i think it looks pretty good, have several cases myself so I'v just been trying stuff,,,, I did a full polish on one, but it was by no means time efficient and i did that closer to how he's talkin, I givem a polish but try not to spend to much time on the quad parts because if you ride much you spend half of yur time polishing stuff.. on the street its not so bad but atleast my quads get dirty and dinged as fast as i can spiff them up..
