After 15 years, a pair of PL-259 connectors have seized on mating SO-239 jacks used on an outdoor RF choke. Is there anything more suitable than Penatrox-A which is Au/Cu rated?  Ideally, I'd like to apply a synthetic + conductive grease on the mating SO-239 threads.

Unrelated, but while investigating the coax connectors, the LMR400-Ultraflex cable I installed about 15 years ago has started to decompose.  At the time of installation, I knew the Ultraflex version has a shorter life span but wasn't expecting such severe decomposition.  The jacket is crumbling due to its rubber composition.  This past weekend, I replaced it with gelled LMR400-DB for direct burial, but it's installed above ground.  Like the original LMR400, the DB version has a rugged polyethylene (PE) jacket.
