Yesterday I was talking about something like this with my CFI and we
discussed the idea of dimpling an airplane like a golf ball. The
upper surfaces of the wings would remain smooth but the fuselage and
undersides of the wing would be dimpled to reduce drag.

That only works on roundish things (helps keep the boundry layer attached as
you start around the back) and only for a limited range of reynolds numbers.
It won't work for your fuselage or the bottom of the wings.
Might work for round gear legs depending on the diameter and your airspeed.

Sailplanes do use "turbulator" tape to keep the boundry attached, but it is
applied only at specific locations.
