[TowerTalk] Protectant for beam connections

[WA4MWM]

I am finalizing the assembly of some Force 12 beams.  Where the balun 
attaches to the driven elements and where element jumpers are installed 
(bolts through the elements attached to balun leads with ring connectors - 
mostly #10 and 1/4" size), they recommend "spraying" the contacts to protect 
them from moisture, corrosion, etc.

What is recommended to use for this?  I need to make this as permanent as 
possible since this area will be inaccessible after installation without a 
crane and personnel bucket.

Thanks,
