A tip for all of your next painting endeavors requiring delicate masking, and or multiple colors/striping……3M’s fine line tape part # 06525 is a paper tape, that is not overly aggressive…..3M’s blue painter’s tape is really designed for the latex world ( house painting as we call it) and is very aggressive. Also, use as minimal tape contact to the work piece as possible. I make masks from printer paper for the model railroad stuff, so even 1/4” tape is only on the work piece no more than half. The other trick is to never try to pull straight up on your mask, but roll it back on itself, as you remove the mask, Your workpiece should be properly abated before any top coats are applied, and this will greatly reduce the risk of lift off of top colors. Your base should be abated before primers are applied, then if working on top of primers, they too should be abated before applying any top coat. Paint will not stick to a smooth, slick surface…..period, ….if you attempt to mask a painted surface that’s not properly prepped, you’re almost guaranteed the dreaded lift off,….below pic is 3 different colors and lettering applied in the above mentioned manner,…note the crisp lines, and bold lettering, and as near factory finish as one can get in a DIY setting,…..
