[QUOTE="PSG-1, post: 392741, member: 6937"] From everything I've read about UHMW, not many adhesives adhere to it, which is why it's usually bolted. If it were mine, I would re-configure the attachment method as follows: Count the total number of holes/fasteners, and make sealed, threaded inserts. To make them, I'd use some short lengths of aluminum round stock, about 2 inches long, and about 3/4" in diameter. Using a lathe, drill about 3/4 of the way into the piece of round stock. Then use a bottoming tap to cut threads. Then drill each hole in the boat to the diameter of the round stock, and proceed to weld each one into the hull, with the bottom edge being flush with the hull. When you install the UHMW, use never seize and stainless fasteners, so they can be removed if needed. This type of configuration, at least in my opinion, eliminates the need to use sealant and washers on all your fasteners, which reduces the possibility of leaks. [/QUOTE]
