[Antennas] Anti-Corrosion Compound

[David C. Hallam]

Thanks, Ron  I live in Clearwater and we are about 4 miles from the Gulf 
but only about 2 miles from the Bay.  I thought the Noalox might be 
better than Permatex.  I considered Permatex mainly because I have a jar 
of it I use when I am working on engines.  Since I had it, I thought it 
would be cheaper than going out and buying something else.  There is no 
point in trying to save $15 or so and then have to do the job all over 
again later.
