Just countersink a bit deeper than normal, use pulled rivets, and then bury it with microballoons. Then, you'll never see the platenut rivets at all.

You can drill and tap flox as an alternative to a nut plate
 
Leighton, our local fiberglass guru showed me that a flox mixture (flocked cotton mixed with epoxy) can be drilled an tapped. I secured my wing tip lenses by putting a blob of "flox" on the inside of the corner, and drilling / tapping for #6 screw after the epoxy had cured. Two screws per lens. (Scuff and clean the surface before putting the epoxy on, build a dam with packing tape to help shape the flox mixture if desired).

I'm not recommending this to replace ALL nut plates, but this is a low stress area that is already fiberglass and the drilled / tapped flox works well here.

Regards,

So far so good. Mine has over 60hrs with no problem. Other Rvs on our field are the same with many more hrs than mine. Just do it as per plans and you should be fine.

Lenses
 
Thanks or the help. I guess I have to start all over since I already drill it for too many nut plates. I will get new lenses and start all over.

Bill, Thanks for the link to Hanson Rivet & Supply. I would think that their PAAD302 rivets [aluminum shank] would be a safer choice for use in fiberglass. The pull pressure is 40 psi lower for the PAAD302 rivets. Less likely to crack the fiberglass, with the lower pull pressure.
