I was thinking about using fiberglass reinforced body filler as an insulator and was hoping someone here may have some experience doing the same. It would be used to support the low impedance end of a gamma match. Power level not to excede 200 watts HF.

Should work OK. I vaguely recall doing it myself once years ago.
I forgot what I did, but I think I had to strengthen a base
insulator on a vertical that was fixing to break or something like
that. Or maybe I had a make a base insulator from scratch..
I forgot..
I used fiberglass body filler that had strands of fiberglass
mixed with the liquid stuff. It was fairly strong once dry,
and I don't recall having any problems with the insulating
properties.
