I?m leaning in the direction of priming only faying surfaces but cannot seem to find much information on it. I ran across an EAA video with the owner of Zenith aircraft and another fellow painting primer only on the flanges of wing ribs with a paint brush but they mentioned little about the full process. A few years back I ran across a video of a guy building what I believe was a -12 and he was doing the same thing but with a roller brush. I was just curious if anyone else who has gone this route could share some insight into the process. I have decided on and purchased AKZO two part epoxy. My understanding is to only prime one of the mating surfaces so this could be a simple and effective way to protect.
As always, thanks to all for your time.
