[QUOTE="Axhammer, post: 502635, member: 16767"] When an aluminum boat is manufactured, solid rivets are used because they are superior in strength & longevity.[I] [/I] If you drill out solid rivets during your overhaul, and then reassemble using blind rivets, AKA pop rivets, you are sacrificing strength for convenience, because it’s easy to slap in some pop rivets, vice bucking some solid rivets. One method to get back some of the lost strength is to use adhesive or glue, while reassembling your boat. I suggest using 3M 5200 sealant on each rivet, and or part interface. Dip or brush a small amount of 5200 on the rivet shaft, and in each hole, before installing each rivet. If you are riveting a flange together, then apply a little 5200 to the flange. It sounds like a lot of extra work, and messy, but this will provide superior strength. This is called a “Wet Installation”. I suggest you wet install every part that is a permanent install. 5200 will create a watertight seal, provide a barrier, to help the dissimilar contact, and it will be much stronger. [/QUOTE]
