Speed Question: Does anyone have experience or an opinion whether it would be worth the trouble to use PRC to “smooth” or “transition” the slight reward-facing overlapping ridge where exterior aluminum skins meet and overlap on the wings and fuselage? (Particularly, of course, the intersections that are perpendicular to the wind direction.)
When added up across all the fuselage & wing surface areas, there are many linear feet of this slight “lip” facing rearward (like fish scales I suppose).
As such, if a person where to transition and smooth every inch of that lip with a reward-beveled strip of PRC (like hard caulk), do you think it would measurably reduce parasitic drag by reducing the "tumbling" of air in these areas, and therefore increase TAS?
