[Moon-net] Building a non metallic Mast

[Wilt Barnum]

Hello everyone,, I have aquired some nice 3in hollow fibreglass to use as a non metallic mast with two 12el yagis side by side with elevation.
Would any of you know of a pourable resin to fill the hollow section making a solid rod? Something that isnt "space age" expensive.
As this will be used at he sea shore in Maine I feel I need the solid section rather than the hollow.
