Hello, fellow Thor(n-in-the-siders
The 2020 Chateau 25V purchased a month ago in Albuquerque had around 1400 miles on it, having been driven to the dealership from the Indiana factory. Any road salt will betray a lack of “due diligence” in coating all rust-prone components underneath.
Nip that $h!T in the bud with a $4 can of Krylon Undercoating! Use short bursts or it can get MESSY! Just spray over the rust. It’ll hold...and you’ll sleep better at night, knowing you took authority over the corrosive environment!
