I got the "rear" piece of decking down tonight. I'm trying to be ready to reinstall the cap on April 10. Not as soon as I'd hoped, but I'm trying to not completely ignore my family and other hobbies.
My order of operations was: sanded gelcoat where the PB will go, cleaned everything with acetone, PB'd along the top edge of the stringers/bulkhead, set deck in place, screwed deck to cleats with 3M 5200 on screw threads. The cinder blocks are there to hold the corners of the deck down while the PB cures. After screwing it all down, I smoothed out the squeezed out PB along the edges, including inside the ski locker. I had plastic down in the ski locker so I didn't make a mess, and pulled the plastic after smoothing the PB.
