How do I grasp mask cartridge stale of metal lacking chipping the paint on the metal?
Answers: masking cassette usually isn't that sticky but you could try soaking it in hose down that should loosen the glue up for you
Remove the cartridge before the paint dries . if you go it on it forms a seal and make the edges stick to the paint. sometmes you can take an exacto axe and score along the video and it will come off within a clean queue but if your line is crooked so will the rank be when the tape is removed. I don`t know try a straight edge. apt luck
