Well since someone brought this back from the dead.................................
I feel bad for you guys the live with 100% humidity 90% of the time. I have seen what it does. Living in a place that rarely goes over 30% has its positives.
My 2020 was built in July, I purchased last year in July 2022. In the first two years of its life it was somewhere east of the Mississippi river. I purchased it and had it brought here out west. It has substantially more rust on it, in/on bare metal places like the OP than my 2002 F350. Fricking amazing that anything back east lasts more than 5 years.
I feel I rescued my Raptor from a poor, slow death of being dissolved in salty acid.
