A scab batch is just as strong as a scarf repair as long as the scab is as large as the scarf. So, a 1/8" skin with a 40:1 scarf would call for 5" all around the cut, with the same number of layers and orientation of the cloth. Sand the area with 40 grit, clean with acetone and lay up a scab patch on the inside and fill the cut from the outside with white filler.
Much to do about nothing!

Yes, this is what was thought to when studying basic fiberglass repairs. Sure, scarf repair is elegant, but not stronger if patch is correct size. We are still talking thin fuselage shell, not main spar.
