Question for the groups…
Is it necessary to remove paint from a skin that you are going to rivet into?
My line of thinking is that the paint could come out from under the rivet after the change – reducing (removing) the clamping action that the rivet had.

It was reported that during WW II, Navy aircraft had zinc chromate primer applied to the skin before riveting to help with corrosion protection even though aircraft were not expected to last that long. T-18 builders in the early '60's also did the same much like Lycoming recommends a thin layer of primer under the hold down plates on the narrow deck / standard cylinder flange engines. Lycoming does NOT want paint under the hold down plates as that creates lose stud torque over time.
ME, I would remove paint before riveting but would be ok with a thin layer of primer under the rivet head.

I agree with Gary. I'd probably go with a thin layer of primer, if that much. I did use primer on all of my parts, when I built the RV-6A; and, I've not seen any signs of rivet movement from that. By the time I started building a RV-7A for myself, I pretty much did away with using primer on everything. I sold the -7A before I finished it and can't say if my changes made a difference. The -6A is plenty old enough to have things show up, though. It's been flying for almost 23 years.
