I recently came across some JB Weld Waterweld and Loctite repair putty. I
have used this two part hand moldable epoxy for various indoor projects and
have met with success on a number of occasions. I am now preparing to
erect a dipole and I am wondering how well this epoxy would work for the
center/ end insulators? My main concerns are UV, weathering and of course
longitudinal strength. Anyone have experiences/ recommendations they can
share?

Thank you.
I thought that one of the parts had some powdered steel or something in it.
Anyway....make a sample and test it in the microwave.

No, according to their website, standard JB Weld and Waterweld are
nonconductive. I have some hardened Waterweld here that I just tested with
the ohmeter and there is no conductivity. They do have a steel reinforced
one thought that would be conductive I suspect.

Why would I want to test this stuff in the microwave?

Dielectric losses.

Make sure you have a cup of water in there while you do
it. But afterwards check the blob of material to make
sure it stayed at room temperature.

Remember that testing with an ohm meter is testing at DC. RF wise, it
might be a different story.

Regardless of matters of conductivity, insulators are cheap enough that
they would be a better choice than repairing a broken insulator. I'd be
very skeptical of the structural integrity of such a repair, especially
if the break was not caused by impact. That would mean that the break
was caused by structural stresses, and would likely recur.
