"Boesheild T-9" is a decent moisture penetrant-displacement-lubricant, that dries to a non-conductive ‘waxy’ finish. Apply lightly to overcoat, as a Sealant-Coating, to completed electrical
connections, let dry without wiping.
I prefer 3M “Scotchkotte”, or “Corrosion-X” Sealant-Coatings,
Ideal “No-Alox”, Burndy “Penetrox” etc Anti-Oxidants.
CRIMPED TERMINATIONS: Apply an Anti-Oxidant to wire, Crimp Joint, then Overcoat w/w Adhesive
Lined Heat Shrink.
SCREW TERMINALS: Apply an Anti-Oxidant between Bus Bar & Wire Terminal, screw tight, then spray an overcoat of Sealant-Coating.
