Jimbo, dont you mean monel rivets, not stainless? I always heard that SS rivets in aluminium had problems with corrosion..
True but everything comes with SS anyway. All the boats I've ever had were built with SS. You could use Cherrymax also, which are stronger than SS and made of aluminum but Monel and Cherry rivets are pushing 50 cent each. Both are a real ballbuster to pull. You really need a air hydraulic puller.
