Im trying to mask flames for some movie prime customs im doing and this has to be the third time ive had to completely re-do the entire paintjob because the flames got screwed up by paint seeping in under the masking tape! Im using automotive masking tape, its not low-tack tape, its applied evenly and theres no gaps between the tape and the surfaces. Im applying Tamiya acrylic red and blue through an airbrush and everytime i peel back the tape the paint has creeped under it and ruined my flames! Can someone please help me out as this is getting really frustrating and is making me feel like i want to throw in the towel on customs altogether - its really getting me down. What am i doing wrong?
