Syco,
My first attempt at polishing the gas tank on my bike wasn't too great. I tried using sanding discs on a drill, way too many swirls and some areas (concave surfaces) are quite difficult to get a 4" disc into. I don't think a palm sander will work on the concave surfaces either because it is flat also. Am I struck with doing it the older fashioned way (sanding completely by hand) before using the wheels/compounds?
