Good morning folks, Today's problem for the wise patrons of Britmodeller is - I have been priming with stynlrez through my airbrush & then over painting with vallejo model air. It looks great - until I mask it & spray a second colour. When the masking tape is removed or the whitetac on occasions - it is taking the paint & primer off - right down to clean plastic. new airifix kit (Bedford mwd) thoroughly washed & dried silverline 2 in 1 brush / 20psi / 4mm needle / 2 moisture traps / littlejet pump primed in 2 thin coats - stynlrez vallejo grey primer also tried as an alternative painted in 2 thin coats - vallejo model air drying time 30 minutes to 1 hour between coats masking tape - tamiya whitetac also tried as an alternative to tape atmospheric conditions - 20 degrees c at all times The result when the tape or tac is removed is the paint & primer lifting - right down to the bare plastic. On closer inspection if you get a blade under a lifted area it pulls off almost like a stretchy plastic film. This first happened a couple of weeks ago with the vallejo / whitetac combination on some plastic food containers I was using for practice with the brush - before moving on to ruining a real model. I initially put it down to the fact that the food containers may have some kind of coating that the paint didn't want to stick to - but I moved to stynlrez as a precaution - as it has rave reviews all over the forum. Now I have the same problem with the tamiya tape on the airfix kit. Previously I was rattle canning using humbrol cans & using tons of masking tape or whitetac & I never had a problem with paint coming off - EVER!!! Any ideas would be gratefully received as always. PS - I'm not going to let it spoil my day this is too much fun. Thanks in advance, Steve
