Hello; I have been trying to get a good covering job on my new Gee whiz Bee, and have wasted 2 rolls of ultracote and 1 roll of ultracote plus. What Have I done wrong? I tack the edges down then when I try to shrink the ripples out, the edges pull off, and everything slides. I have been hording those last few rolls for abour 3 years, could they have gone stale? Is it possible that it goes bad if the ultracote gets too cold? This ultracote has been stored in my (not heated) garage, and certainly has seen many days below freezing.

I have the coverite thermometer and tried 175*, 200*, and 250* degrees, but it doesn't stick at any of these temperatures, same story with the ultracote plus. I used to swear by ultracote, but now I'm going out to find a roll of monocote, and I bet that works.
