I bought a couple trays of Portable Warfare's Blu foam from my LGS. The first 2" tray was falling apart at the blu base. So I went back and exchanged it for a new one that was not coming unglued. I took it home and began plucking the foam and loading a few bone chickens in the empty spaces. By the time I got to the 3rd chicken, the Blu foam was coming unglued on this new tray. Pretty frustrating, as I have heard good things about PW's Blu foam and the LGS had no problems with their quality before. I'm not going to bother asking for an exchange from the LGS since I already plucked spaces out. I was wondering if anyone knows the best way to remedy this problem. Should I just use PVA to stick them together again? Or do I need something like a spray adhesive? Thanks in advance.
