I like the idea of spraying on a protective coating. Glyptal clear
insulating varnish spray was suggested earlier and was reported to last
quite a few years when sprayed on aluminum antennas. I have done a
little research on clear insulating varnish and found two that might be
suitable. One is Glyptal 9620 which may be the one that was reported
here earlier, and the other is Sherwin Williams S00600. Both products
are spray on clear insulating varnish. They are glossy though if this
is an issue. If they will last as long as the one reported earlier I
will give one a try. Here in the SF Bay area aluminum corrodes pretty
quickly, I would love to find a coating that will work for my aluminum
antennas. Any experience with either of
these ?

I agree, why do you want it shinny? All of the 6061-T6 tubing that I buy
comes with a dull finish and it looks great in the air.

Why on earth would you want it to be shiny? Seems like it would be more of
any eyesore to any neighbors that way. It certainly doesn't make any
difference electrically.

Is there anything that will keep an antenna shiny and bright, besides not
putting it up? I have often heard clear Krylon mentioned, but from my
experience, it is very short lived. Three coats, allowed to dry between
coats only lasted a few months if that. Around here (central MI) the shiny
Al turns to a dull finish in a month or two.
Alodyne does last and looks good, if you like a shiny gold color and have
both time and ambition. I have used Alodyne on aircraft elevator hinges.
It's a very labor intensive (tedious) process. The antenna would certainly
stand out.
