Got a boat that had the rear bench seat partially cut out by the previous owner but he didn't do anything to seal up the sides. The way the boat is set up there is about a 12"x12" box thats flush up against each side of the seat and the seat is cut even with that. Would it be worth giving this durafix stuff a shot to try and tack on a piece of aluminum to seal up the side of the seat? Ideally I would just get it welded but I don't know if I can justify the price for this boat? yall think it would work?

anyone try this before?
