I had a ham fried who was the radio office on a sulphur ship. Over
the years he tried everything to attempt to protect his
antennas. Needless to say, between the salt & sulphur fumes nothing worked.
On one occasion he sprayed Krylon and found that once the paint
cracked it allowed moisture to creep under the paint and caused more corrosion.
This was more than a few years back so my question is: are the
current acrylics more flexible and less prone to cracking? Once it
does crack will it not cause for more problems?
