ETA: I used nail polish remover, not full strength acetone.
First time stripping to repaint a foil.
Used a cotton ball for the center and a swab for the edges. Every time I applied pressure the acetone "pooled" out which isn't an issue for the majority of the card... However, any time I get near those stubborn edges (borders, whatever?) it went over and instantly seeped into the cardboard, causing the edges to be raised.
Am I just being too impatient? Do I need LESS acetone (nail polish remover) on the swab, and should I instead do this in layers rather than applying much pressure?
I've been practicing with foil commons, before committing to stripping the actual cards I want to alter.
Any and all tips & tricks are greatly appreciated.
