Rust ? You think you have rust ? You live in SoCal - you don't know rust.

Come to Western PA and you will see RUST. In this area, people get rid of rust by flying to SoCal, or Nevada, etc and then drive the rust free car (or items) across the country back to Western PA.
.
Just a bit of humor - I know areas near the ocean can have issues with rust .......Seriously ....
.
There are products that neutralize rust (Naval Jelly), neutralize and convert rust (and form a coating) (POR 15 or whatever number, Permatex, Rust Oleum). and primers for rust coated surfaces (zinc rich primer and Rust Oleum has a primer (Rusty Metal Primer) that (supposedly) uses 'fish oil' or something similar (first the 'snake oil' salesmen - now 'fish oil' stories) ........
.
There may even be a lubricant with 'staying power' - a motorcycle chain lube for example - that you could spray on the areas for minor protection. ???
.
and there is my .02 cents ............
