Hey Kropy...
Well it looks as if I'm the first customer in the questionas and answers
I've been painting shells for friends and myself for years, I've been using a sticky backed plastic for the masking, recently I've run out of masking film... I've tried several different brands of sticky films, but the problem I'm having is the glue is being desolved by the thinners in the paint(Pactra), so when I remove the maskings it leaves a sticky mess, this can be removed (although it's a right pain!!)...
Here it comes... What masking medium/film do you guys use?? Also I presume you cut most of your designs out on a die cutter?? I use a good old scalpel and patience...
I've attched a couple of images of recent shells, please cast your expert eye and give me any advice or feedback, good or bad

...
Cheers
