After reading reviews and searching for vendors I found the best deal is with the manufacturer. Beware of other retailers, they are marking it up as much as 150%.
A lot of people complain that it is hard to work but a 6" high density foam roller took care of that. The roller enables you to get a much thinner coating thereby saving you $$. Speaking of thinning, you can but you loose quite a bit of adhesion. I thinned it down to 50% mask 50% water. It went on quick, easy, and thin and then promptly blew off in big pieces under the air assist of my laser. Bottom line; use it as the manufacturer directs and you will be very pleased.
I found this to be an excellent mask and far less expensive than other places, however it is by far the toughest to work. While others have a consistancy of molassis, this is more like molassis in January. Because it is so thick it makes it hard to get a good coat on acrylic which in turn makes weeding a little more work.
