It's a simple, light weight (probably two ply) tube with some kind of
white paint. Probably epoxy. 5 years in the sun and you can't get near
one without getting covered with a white dust, at least that happens
with both the Comet and Diamond colinears. I have two side mounted on
the 45G and one mounted just above the eves on the North side of the shop.

I believe it was Comet that used plastic couplers while Diamond used the
chrome plated ones. I have both types up here.
