[TowerTalk] Noalox versus penetrox ??

[Patrick Greenlee]

Ditto experience with Noalox superior to Penetrox in marine environment 
(SOCAL experience.)
Note: Regarding cleaning/polishing aluminum, by the time you are through 
cleaning and polishing aluminum it will have oxidized if not protected from 
atmospheric oxygen.  You may not see the oxidation but it is there.  This 
rapid oxidation forms a protective layer that inhibits further oxidation. 
The sharp conductive particulate material in Noalox penetrates this thin 
layer of oxidation and makes for good electrical connection.

Say again, why I don't see the new oxide layer...  The microscopic crystals 
of the oxide are saphire and are essentially transparent.

I prefer the Noalox, as it does NOT get hard as concrete like the Penetrox.
