I have always used a local company who uses an oil based rust protection system. I really don't know the product name but I can find out. My daily go to work car was a 2009 Chevy Cobalt that I bought new and had it treated and touched up annually here in NW Ohio. I sold the car last summer with absolutely zero rust. I never replaced any fuel lines nor brake lines. Still had the original exhaust system after 243,000 miles. I also ran it through the car wash once a week through the "salt season". I was so pleased with the results that I had my 2018 GMC Sierra done when it was new as I plan on getting 200,000 miles on that as well. In regards to my SSR, it gets put up for the winter but our winters are a bit milder and shorter than yours. 
We do have an SSR owner here in Defiance that does drive his SSR all year round. He takes off the OEM rims in the winter and just runs steel wheels with snow tires. Seems to drive just fine for him as its his work truck of sorts!
Again welcome to the family! Keep an eye out as we will have "Meet and Greets" with little Day Rallies here in NW Ohio. Come on down and join us!
