I haven't checked my lotto numbers yet.
I'm going to use my rustproofing air gun and attach a flexible hose to blow my secret rust abatement formula into the body mount captured nut chambers.
The secret ingredients start with either (1) Fluid Film, Rust Check oil, used auto trans fluid, used differential oil
-either (2)foundation coating, roof sealer or body undercoating thinned with lacquer thinner or WD40 till runny
-combine some of 1 and 2 to a sprayable consistency
It's messy and may need to catch dripping but it solidifies to a wet, sticky coating that works great in hidden compartments and along body seams.
All I can say is that it works for me on my daily drivers for the last 25 years here in the salty north.
