Matt,
Get out your copy of AC 43-13, Approved repair of Aerospace vehicles and
read up on cracks.
I think the approved method is to stop drill the end of the crack and then
watch it.

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'm just about ready to take the plane in for paint, so if I have to do
something about it, I'd rather do it *before* the paint.

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).
