When you unfold it and apply it (bathtub sink) the ease and adhesion of application is fine. However, the main problem is that the surface that comes out is uneven and looks wrinkled/crumpled after application. I assume it's because it curls up and forms permanent creases. No matter how I tried to smooth them out, they wouldn't go away. And I tried various methods to smooth it out before just removing it and throwing it away. Update: I bought a larger thickness (1 inch) from another brand and it has worked and looked great. No wrinkles. So it looks like the problem was that the smaller 1/2 inch thickness is a problem with curling.
