Hello, I just purchased a used Owens 55033 single dog box for the back of my pick up (no topper). I'm looking to better insulate the box by covering the entire interior with some type of closed cell foam insulation that I can glue-appoxy to the walls, roof and floor. I found a site on line (closedcellfoam.com / gym rubber) and it seems like a good choice for my needs. I would post the link but apparently I don't have enough posts on RTF for me to be able to post a link (sorry). I've never done this before and was wondering if anyone with experience could give me some direction or point me toward a better product for this application. I hunt almost daily and travel abouy 80 miles round trip from Sept to Jan in midwest (Illinois) weather. Dog isn't a chewer. Thanks in advance.
