I decided to sand the cabin top and apply a coat of epoxy to seal the fiberglass.
Sanded cabin top using an RO sander and 220 s/p just enough to remove the glaze.
Mixed two pots of epoxy, one small one with micro, the other just raw epoxy.
The micro was applied to the door pannels where there were minor voids from the mold process.
The raw epoxy was then applied to the main portion of the cabin top using a plastic squeegie. I wanted to ensure the fiberglass was sealed under the antennas prior to installing them.
