For those who labels are under the clear, use 2000 grit wetsandpaper. Get a bowl of warm water with lots of soap. Dip the paper in the water and sand in one direction very lightly. Once you fell the labels, peel them off with what you have and once ther gone, wetsand till everything is smooth. I mean very lightly......once your done, get some rubbing compound and rub your ass off!!!!
Buff it out, and your good to go.
And when I describe lighty, get a piece of paper and rub it on a table, that's how little pressure you need, and remember, use lots of soap and water, if starts to dry up, squirt more water on it, do not do this dry by anymeans!
