To save you a ton of reading, I will cut to the result. They liked a product called Corrosion Free 3000 that is available at Canadian Tire (Canadians buy their clothes at Crappy Tire BTW)
I get my cars sprayed yearly with a rust spray (usually Krown) and they certainly have never had body rust in the 30 years I have been doing it.
There are some references to US Military corrosion studies...despite the shutdown. Hope this does not contravene any US regs.

*you can skip through the French part as they don't care about Corrosion in Quebec....can't be defeated there.
