I find the product provides low adhesion - so it didn't damage or lift paint.
It also gave excellent "bleed" sealing - so an accurate line was easy to achieve.
I found it easy to cut - so awkward designs were easy to mask.
I was hopeful that this would be the answer to my dreams but alas not. Even though I only had it on the wall for a couple of hours whilst we painted when I peeled it off (very slowly and carefully) it took off quite a bit of the paint underneath which needed touching up afterwards. Maybe if it was less sticky it would not have been a problem.
I purchased this to attach to crafting dies to hold in place when cutting, and to remove it without pulling the card to pieces, this does exactly that.
