Bill, I know we all learned that aluminum oxide limited bond strength, but I'm not sure that that is always true. The H8000 is reported to have a shear strength of 3000-3500 psi on both steel and aluminum, and the T-Peel is actually higher on aluminum than steel. There could be lots of reasons for this, but it does suggest that the oxide is not the limiting factor. Perhaps the adhesive penetrates the aluminum oxide layer. Also, I don't know what the definition of structural is, but at 3000 psi this stuff may qualify.

Is this adhesive really suitable for kayak frames? I don't know yet-I'll report back in a few years.
