Re: Rivets, pop rivets or screws
Ummmmm.... Ok.... I'll take a shot.
Assuming this is a aluminum boat what u use will largely be determined on what your going to use the boat for.
A closed end rivet can and should be used. Stainless. Steel rivets could be used if the boat is not going to be used in salt water. The use of 2 dissimmular metals in that close of proximity will gause corrosive galvanation, this is bad.
Aluminum closed end rivets are your best choice.
Aluminum bolts can and have also been used with a dab of 5200 during assembly. My brother jon bolt is held together solely with bolts, it works well and doesn't leak with the 5200.
Sheet metal scres are a BAD idea.
What about just tightening up the rivets that are allready there? It takes 2 people, but really is the best of all options. Search "bucking rivets" for more information.
