Not the type to normally write a review on a product but this stuff is the only tape I'll ever use for painting. I asked my girlfriend to purchase FrogTape for a design I was going to do on our wall. Never used the product before but had heard good things. She had FrogTape in hand at the store but the employee suggested just using regular painters tape that cost pennies less, BIG mistake. I was hesitant about using it but figured the "paint guy" knew best, so went ahead with it. I taped off my design, which took hours, painted and then removed the tape. It bled through on the edges! Was less than happy. Went back to the store and purchased FrogTape. Taped off a thin border around the design and painted it white. After removing the tape, the lines were PERFECT. Awesome product!
Though Multi-Surface tape indicates that the PaintBlock technology is only on the edges, you should be able stencil with a sharp blade, without the paint bleeding. As always test before applying.
