[TowerTalk] Loosening Rusted Hardware

[Roger (K8RI) on TT]

It just says <25.   What is the volatility of that Hydrocarbon?

  Spray it on a flat surface and leave it out in the sun all day. How 
much film is left?
I have never seen it remove corrosion other than a film of surface rust 
that can be wiped off. , nor will it prevent steel from rusting on an 
antenna.  Spray some steel U-bolts, and just hang them on a tower.  How 
many days before they show signs of rust.  I recently rebuilt a damaged 
antenna. About half the nuts twisted off the threaded portion.  WD40 
didn't help. PB-Blaster did
