On some of the compound curves I have to cut some slits in the glass cloth to get it to lay down, and corners need to be cut too. I agree the WB poly doesn't seem to stick the glass down tight at first but after a few coats and hardening up for a day or so it's a pretty tough surface. I like it because it's so easy to apply, sands easier than epoxy and you can sand out overlaps better.
