Dissimilar metal corrosion: avionics tray?
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.
SeaRey builder lurking to get ideas to make his plane better, and keep his build from stopping like a gear down landing in water.
Dues paid for 2022
