Anybody know of any glue that will hold two pieces of sheet metal together? My kids have been badgering me to put a wakeboard tower on our boat, so I bought one online to install myself. It has four single-bolt anchor points around the hull. As both the installation instructions and common sense tells me, I need to reinforce the hull at the anchor points or the fiberglass will likely crack at the anchor points from the stress of pulling on the tower (actually I assume it will crack regardless, but would like the reinforcement so the bolts don't pull through).
I got a piece of 1/8" steel sheet metal and cut it into 6" x 8" rectangles (I "fabricated" the pieces for "the build" if I was on a DIY tv show) to glue to the inside of the hull after drilling the mounting holes. I cut 8 pieces, with the intention of doubling them up for a total 1/4" reinforcement. I'm okay gluing the inside piece to the hull, as I think some heavy duty Loctite will hold that bond okay, but anybody know of any glue that will hold the 2 pieces of sheet metal together? I have no welding equipment and have no desire to get any. Worst-case scenario I will just wrap duct tape all around them to hold them together, as once the bolt is through it will hold it in place, but I'd like to make the whole mounting point as strong as possible if there is a cheap commercial product available.
