Default Holt melt glue as potting agent ?

Thanks for that input - I did put some in the microwave and it was fine
as you said, and I have wrapped / smeared some around some 14 gauge Cu
wire and bent it around and it adheres remarkably well ! Any idea how
it suffers UV ?

Not bad at all - much better than epoxy, for example. It turns slightly
more opaque, but doesn't crack or peel.

It only really needs to last a year or so as by then I am re-doing
aerials and things...

You don't say where you are in the world, but in these latitudes ( low
and mid-50s) I've used it for several years without problems. For a year
or two, I'd guess it would be fine almost anywhere.

Southern UK - Hampshire, and much of the time it is locked up in
the garage in the dark - so maybe a century ???

The other product I have found to work extremely well is Evo-Stick
impact adhesive... it seems to tolerate sun forever and is still a
little flexible
after years too - but as more fluid only really any good for thin
films / coatings...

Thanks,

Nick
