Filling Drill Holes in Fiber Glass Roof

I removed the battered dish antenna from the fiber glass roof of my coach and now have two drill holes, roughly 1/4 inch in diameter, to fill. Does anybody have suggestions as to the best material to fill those holes with? Many thanks.

    My vote would be high temp two part epoxy. Let it over spread the hole some.I say high temp because the skin could fry an egg in the summer sun. For insurance you could put an Eternabond patch over over the finished repair.
