Which adhesive caulk for solar panel mounts??
My CW has Sikaflex in 221, 505 and 715. Which one is best to mount solar mounts to thin fiberglass roof along with screws?

I believe that "non structural FG" - all those roofs except for Scamp, Casita, etc - have nothing but block foam underneath. Such things should better be checked by prying the trim off, inside the vent hatch.
Could have 1/8" ply backing, but this is still nothing. On surfaces thinner than 3/8" I prefer well nuts. Tapping screws won't hold.
