I'm installing the empennage fairing, which fits very well, but have a question about the mounting screws. The plans call for using AN509 8R8s, which are countersunk, flat head screws. The fiberglass on the fairing is way too thin to countersink to fit the screws. It seems more suitable for non-countersunk round head screws, but these of course would add parasitic drag. Does the fiberglass need to be built up? Looking at the construction video and other sites, I haven't seen any mention of this or using other than the screws called out in the plans. Any suggestions?
