All modern cars sold in North America are rust proofed from the factory. Both the US and Canada have legislated anti corrosion warranties. Canada requires a six year no perforation warranty.
Dealer installed rustproofing is just another dealership rip off.
By the time a Japanese car gets to a dealership in North America it is far too late to add any rustproofing without thorough cleaning and drying of all the required areas.
Rustproofing exterior surfaces does next to nothing. Rust attacks cars from inside the panels. Applying rustproofing aftermarket is as likely to seal in rust causing moisture and air as exclude it.
Two types are used: flexible epoxy coatings for exposed underbody and waxy coatings for inside box sections and insides of susceptible panels. Ordinary car body paint is the primary anti corrosion method with galvanizing or electrophoretic painting of the bare metal followed by the final colour.
No modern car should rust significantly for at least ten years.
