[TowerTalk] Protecting Screws on lightening protectors; Use for wire brushes on top of towers?

[Fred Serota]

two quick questions:

1. Most of the lightening protectors for rotor controls and the SteppIR 
control lines involve exposed screw heads (albeit stainless) and bare lugs. 
Are folks spraying these connections to protect them over time? If so what 
are you using?

2. Is there any benefit in protection against atmospheric charges in using 
the steel brushes that are sold for these purposes? What literature I have 
found has been equivocal on this.
