Re: getting TB II or gripper to stick to foam, I found in testing either will just peel off the foam unless you give it some tooth. With tooth I found the bond strong enough to tear the old worn out bedsheets I was using. I use a warner 250 tool wallcovering perforator to rough up all foam faces, I had no joint failures in my foam boat thanks to the extra depth it gives each bond. I believe a foamie tear will take abuse better than most, I high centered the boat on rocks and logs more than once, I forced the boat off of them rather than tipping it to allow it to float off, other than grooves that we all know could be removed with a steam iron,the foam is fine. I only used regular old bed sheets to cover the boat, not canvas tarp or denim, there were no tears.
