Window Sealing Film

[Wild Type]

I did a two day trial of shrinkable window sealing film as a ground cloth for tents and as a sleeping pad base in shelters. It worked great. Has anyone used it for the long term (say greater than 2 weeks of normal trail use)? Just wondering how it holds up.

It's great stuff, also called polycryo (Granite Gear sells it for a lot more $$). Bigcranky has used the same sheet for 5 years. See this thread: http://www.whiteblaze.net/forum/showthread.php?t=69750&highlight=polycryo
