    I don't mean to be a pain, but a thought just went flashing through my inhibited farming brain......

    If the disturbed air is so much (3 inches on the trailing edge), would it not be similar to a set of stall strips on the leading edge in other aeroplanes, and should I install the gas cap fairing, I might end up with harsher wing drop characteristics in the stall? (tip stall with a bigger arm/moment).
    I have a fairly docile staller in the plane without the fairings (can keep it sinking using rudder).

    Am I splitting hairs??
    Trying to be too clever?

    They streamline the air flow behind the fuel caps thats all,

    I noticed a smaller V fuel stain behind the fuel caps after than before the fairings.

    There has to be a fair amount of turbulent air behind the fuel caps without the fairings.

    I was doing some touch up painting at the 2 rib/ fuel tank area , so I decided to put the fairings on.

    I scuffed the the area real rough , used structural epoxy, super fill, UV smooth prime,EP420 epoxy primer, then aerothane. Maybe overkill ? I was using most of these things on other areas anyways.
