Be careful when you're doing any power polishing. Chris is correct in that it's possible to go right through the clear. You're better off to try a very mild compound first unless the finish has bad scratches or scuffs. Two that I use are Meguiars "Scratch X" and 3M "Finesse". Do a search and you'll find them mentioned often by the CM's who frequent this forum. My business is cars, and the areas most fouled up by a novice are always the peaks, edges and tight curves. Your cue is 29 inches of curved surface. It's a lot easier to screw up than a big flat hood or door. You can always go more aggressive with your compound in any bad areas if necessary, but you can't go back once you have polished too hard.
