OK...the plane is already built by the previous owner. upon closer inspection, I find that the covering needs to be removed to repair a split on the bottom of the wing. This initially didn't appear when I purchased the plane but after sitting for a couple years it's apparent that there was some damage...nothing major at all but still should be repaired.

So I'll be pulling the covering and making the repair. Regarding the dihedral brace...should I split the wing and basically reinforce the brace from scratch or will glue and screw the Alm or CF to the front and back where the wings join do?
