i use oracal paint mask & mathews paint all the time, no issues. possible you're coating it too hot&heavy?
paint mask resists solvents, but the perimeter is the weak spot.... its like having clogged gutters, a little rain is no big deal but a heavy downpour and suddenly your basement is leaking.
thanks for the compliment. I can do a basic trimless channel letters like this 6 in. Letter A in prefinished white with acrylic face for $100 min. or $12 and upright inch for the time being so dont be afraid to send me a quote request. We are a small company and cant handle too much work. Just had to turn down a higher end job for 300 letters cause they needed it done in 2 weeks. Kind of sucks but as much as i wanted the job i couldn't in good conscious pretend i could get it done that fast.I forgot about Gerber mask, but I've only used that on a non angled orientation (flat graphic stencils), and I think that is the real issue at hand. I'd almost recommend instead of camming the edges and painting them, cut your vinyl 1/16" smaller than your face, and then plot mask 1/8" smaller than the face. This way when your remove the mask you have paint over the edges of the vinyl. It does diminish the effect, the cam looks sharp, but since you are shooting at a 45deg angle to your mask, you're going to fill the void at the edge of the letter.
Just a thought, are these laying face up or face down when you shoot them?
BTW, I think your stuff is awesome, I wish I could find customers that want a superior product as opposed to a cheap one.
Is there a good masking to protect vinyl from matthews paint without bleeding. I have had some luck with a product called oramask that is blue but it leaves adhesive on the vinyl.
