Is there any thing you can byt that is good for removing large amounts of filler? Or is it the case of haveing to rub it back. Basically over done the filler by a long way and may take a while to rub back.
id say just keep rubbing it down use a coarse sand paper once you get near were you want switch to a fine one to smooth it of just perseverance Ive put to much on loads of times you just gotta sand it all down and learn from your mistakes.
Put it on, rub it off.
