I purchased a kit from a builder that couldn't continue. Quite a bit of alodining/priming has been done on a number of parts, mainly empennage ribs, spars, etc...
Most of the parts have not had their holes drilled to size or dimpled, yet they are alodined and primed. Obviously in drilling these parts, I'll leave the inside edges of the holes exposed & based on anecdotal evidence, I can expect the epoxy primer to chip when I dimple.
Seems to me that a rivet hole is precisely where corrosion might start & I need to retreat these areas after drilling/dimpling.
Thoughts?
(Charlie, I know I got your input - I'm looking for some sort of consensus (LOL, around here... right ))
