One of my local experts says I can't use nutplates on my 4043 aluminum avionics tray without powder coating it or I'm going to get dissimilar metal corrosion between the nutplates/cherrymax rivets/4043. Other areas of the SeaRey have nutplates riveted to the aluminum frame (6061T) with cherrymax rivets, so under his logic the build is already flawed in design.
Thoughts?
