Default Full prime on mine

On the RV-7 that I partially built I did the rattle can seaf etching primer on all surfaces. When I start another plane some day I'm going to do the full etch, alodine, and epoxy primer to all surfaces. I'm going to keep my next RV for a while. Plus I have been working on non-primed certified aircraft for a while now, and have seen more corroded aircraft than not. Even the wings of my 182 (which are not primed) have some corrosion in them, and it was stored in a hangar for the last 25 years at KVNY.

If the area of the skin that has light coverage is really 40% primer, and 60% bare aluminum, is that really helpful when it comes to protecting from corrosion?

If my skepticism is unwarranted, someone please set me straight.
I don't really know - it was the recommendation of an EAA tech counselor
