Jon Boat Remodel

AMC23 · 03-09-10, 09:21 PM

So here is my situation. I have a 16' semi v jon boat that leaked like a sieve when I first bought it. I put it in the water and tried to find all the leaks and marked them, but it got to the point that there were to many. Instead I used NP1, which is a polyurethane based sealant, and caulked all the rivets, seams, and screws from the inside and out. Now, 4 years later I am doing a complete overhaul. New floors, decking, transom... the whole 9. I wanted to know how to make it as water tight as possible. I don't want to have to take the floor up again. Is there anything I can spray in the bottom over all the NP1 I already have in there? I bought some of the bostik 920, but I would think with all the synthetics on the market something has to exist I can coat the inside with that will seal it. I have heard the spray in bedliner doesn't work, although that was my first idea. Thanks for any advice!

If you have an air compressor, try to locate a rivet gun (some call it a rivet hammer), and a bucking bar (a hardened metal tool to hold against one side of the rivet while setting the rivet with the gun on the other side. This would be a two man operation and very noisy and tiring, but well worth the effort. After re-setting all of the rivets, the a two part epoxy paint on the bottom should seal things up pretty well.

Riveting every single rivet is something I thought about doing but I do not have any of those tools. I was looking for a reliable but a little less extensive of a fix... on another note I want to post some pics but I can't get them to upload from photobucket. What gives?
