Having some trouble with the white curved tape sticking to the angles where the top meets the sides. One tape line lifted so bad, it would've allowed paint to get under it. Had to cut that line out.
Pro-Line Liquid Mask is pretty good so far, easy cut and peel. Was worth the error to test it, in order to know what to expect when changing airbrush colors.
If those white tape lines bleed at all, or don't appear to be sharp and even, the effect will be ruined. Going to keep trying the tape lines and LM, until it's right. Prep is everything in painting, and the hardest part, imo.
