I've tried applying it by hand and buffing it out, tried applying it with the porter cable let it sit and buff it out with a clean pad. It always leaves a residue that is nearly impossible to get off, it just smears when i try to get it off. Any ideas are welcome. Also, I've got some deeper than normal scratches in my paint that meguiars scratch remover and the orange pad won't take out. I'm about to get their fine cut cleaner, but i'm afraid to use something that i can feel the abrasives in. Anybody used that with the porter cable and what were your results?
