[Moon-net] Antenna corrosion protection

[Darrell]

I have used Krylon UV-Resistant Clear Gloss  1305  here for 20 years 
or so and would not change for anything
It is available world wide through many outlets, and each store 
number will be different BUT MUST end with  1305

Regards & Thanks, Darrell
