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?

SFVdave,
The isn't any different and DuPont 5200 would be my first choice. I used it on the brackets of my Kyoceras and 31 years later the stainless brackets ar just fine.
There is nothing wrong with cutting 6" X 6" 16 gauge steel pads for panel mounting. Glue the pads to the roof with 5200 laying a brick on top for compression. I used stainless RivNuts and stainless bolts cut exactly to the right length, then applied Red Loc-Tite to those bolts. They have withstood hurricanes and even the reported 145 mph gusts we got down here with Gilberto.
