Oops, should have called before I started. I guess the next sorry sob who buys this boat will be calling you to ask why he can’t get the darn deck off, cause some fool must have glued it on with 4200!
I could not seem to dig all of the caulk out with the deck in place, so I lifted it up a couple inches in sections, and cleaned up the hull sides. Covered with a lot of 4200, dropped back in place and then screwed all around using the original locations. I think I hit 25+ screws up each side before finding a solid one, so a lot of new holes. Once I screwed it tight with the newly drilled holes, a nice looking bead of caulk was showing in the joint the whole way around. For a few minutes I was thinking about thru bolting the sections that failed, but never got there.
Should be ready to put the rub rail back on tomorrow. But now thinking about ordering a new one, or at least a new insert.
