I have been using sign vinyl for quite some time. It's the same vinyl that is used by graphic shops on their plotters to cut decals and signs for cars/trucks and comes on a roll. It works great and does not peel if applied to a dry, clean and cured surface. The key is to ensure you finish is fully cured. The only caveat is that it sticks really well, I use a hair dryer to warm up the adhesive and pull it off slowly. So far it's the best mask I've used and I tried many of the commercial products out there. Hope this helps!
