Hi Thomas,
Thanks for your positive comments. The polyurethane caulk I use is called "Vulkem". It is a freaky strong caulk that historically has only been available through contractor supply outlets. However, it seems to be turning up more and more in Home Improvement Outlets.
Less expensive polyurethane caulks are not as strong and probably don't offer much over silicone. Especially when you factor in how long they take to dry.
I may just try silicone next time. Heck, if it will hold glass sheets together in an aquarium large enough for me to swim in it should work in this application.
But regarding the Vulkem, and other polyurethane based caulks, they are fantastic and holding together disimilar materials. Probably the one weakness of silicone.
