TRIMEX TM Window Mask (WM) is a high quality, acrylic coating having two to three times as much resin as paint and is designed for masking door and window glass.  The coating bonds strongly to wood and previously painted surfaces, but it can be easily removed from glass.  The WM coating seals the non-glass surface like a primer.

Trimex Window Mask was formally sold as 3M Liquid Mask by the 3M company. You can still get this quality product through this website, or by using the contact numbers below!
