Matt,

 I would consult with an IA and also refer to the FAA manuals.  The  painter may have some advice also.  I've seen cracks stop drilled in skin,  but that obviously leaves a visible scar.

 Who is doing your painting?

 Also, I am interested in how well your changes to the aileron hinges solved  your heavy wing situation.  I have the same problem and I'd like to solve  it without the use of a trim tab.

 As I understand it, on the HEAVY wing side, you opened up the aileron hinge  attachment holes to allow slight movement (1/16") and moved the aileron downward  in relation to the wing structure.  Do I have it right?

I dropped the outboard tip of the right aileron about 1/32" by elongating the bolt holes in the white powdercoated steel hinge.  I had a heavy right wing.  Before I did anything, at cruse I needed full left trim.  After moving the aileron down 1/32", my trim is now centered to about half a bubble to the right.  I was *amazing* how little movement made such a huge difference in trim.



I recommend starting with just a LITTLE bit and working your way up to neutral.



Way better than a tab or squeezing the trailing edge!

RE: Paint.  I'm taking the RV-8 up to Red Bluff in California to a place called Cardan.  I've been discussing the job with David Underhill there at Cardan Air Services and have been very impressed with his attention to detail and understanding of what it takes to do a quality paint job (not necessarily a "cheap" one).
