Rated 1 out of 5 by Screwed from GARBAGE First time we used it, product peeled fine and left a proper sharp line with minimal residue behind. As we have gone through the roll, the mask still leaves a sharp line but now large amounts of the adhesive are left behind on the panel. Now I am stuck in the middle of a big job cleaning panel after panel. Will not buy again. Note: Panels were properly cleaned and prepped, sprayed MAP with correct reducers (no additives), and peeled at different intervals of time after spray. Amount of residue left behind has varied as we have cut through the roll.
