Yeah, it was all going good until I realized that I have dimpled some holes I shouldn't have. Specifically, the 10 inboard holes on the RV-8 horizontal stabilizer where the nut plates for the fairing will attach.
Left to my own devices, I would probably use some countersunk rivnuts like these:

..I know rivnuts are despised by many, but I think there might be some ways of mitigating future problems:
1. Rough up the underside of the shop head and the dimpled hole and apply some epoxy before setting the rivnut to keep the nut from rotating later.
2. Blue thread locker for the screws, since the rivnuts don't lock. (Is that considered acceptable?)
I've been referencing this KitPlanes article which mentions the epoxy:

BUT, hopefully you have a better idea...
