hey thanks for the tips..... but cartridge rolls only go to like 160 grit!!! what about going to 4-600 grit!!! are you just supposed to compound the hell out of it with felt bobs after 160 cartridge rolls? and gafmo what do ya mean by
"I just use a piece of wire rounded off"
? "and start with a 120 grit wet & dry and then move up the grits"
? thanks guys
