Been using the 3M Super 77 since I started scrolling and was always happy with it until the last two cans I purchased. Then the patterns started lifting up while I was scrolling. Do not know why, but decided to try other products. I bought a can of Loctite High Performance 200. Didn't read the instructions until I got home, of course, and it says to spray both surfaces! Now that is a real pain in the rear end. It works great, but too much trouble. So I will try something else next time.
