I'm getting ready to take my wings off to install platenuts for the fairing, and I was wondering about dimpling the holes. Do most people dimple here, or countersink? The thin areas like the tank skin would obviously get dimples, but are the rib/skin areas too thick to dimple?

Thanks!

I dimpled the fairing top and bottom. I dimpled the wing root bottom and tank. I countersunk the wing root top where you have 3 layers of metal (rib, wing walk doubler and skin).

I agree with Steve. Dimple where metal thickness is dimplable (is that a word?) but countersink where the metal is thicker (or multiple layers of metal. Ultimately, I have found that a countersunk screw sits better/flusher than a dimpled one.
