Felix, JWA, Dave, Ray, and Brian, brilliant ideas, thank you all!
Some VCI sheets, WD-40 LTCI, gel rust remover, as well as a couple of buckets of chem dehumidifiers purchased, experiments to follow.
Still thinking the biggest contributor to the condensation/rust issues was the Monterey Peninsula/Big Sur area where we were for the month of October with sunny 75F+ days and evenings pushing 100% humidity, 50F with thick ocean fog rolling in causing everything to be dripping with moisture.
A beautiful part of the world with unexpected consequences. Regardless, well worth the condensation troubles as it was a great trip!
Best, Em -
