I found some spray adhesive by Krylon in the local craft store. It is half the price of 3M77. Has anyone had any experience with this product for sheeting foam wings? I brought home a can and it doesn't list foam on it's recommended uses, but it doesn't say you can't. I tried it on some white foam from my last radio box. A light even dusting didn't seam to bother it but a heavy wet coat ate at it a little. I don't know much about foam but it looks close to what a foam core would be. Does 3M77 eat at the foam if it gets too wet?
