Thanks, but I am not talking about priming the rivets prior to installing them, only after they have been installed. As for the passivation, isn't that a surface treatment and after the rivets have been squeezed, is somwhat lost?
It just seems that if we prime alcad, then why not passivated rivets after they have been pounded and have lost some of that corrosion protection? However, if there is no real record of rivets corroding, including in coastal areas, then that is good enough for me. I sure don't want to be dabbing on primer over my freshly bucked/squeezed rivets.
