Assuming they don't salt the roads in KY, I would look elsewhere. While none of that rust is anywhere near structural, it has started and you'll never get rid of it all. All of those fasteners will be a big PITA if you DIY, better have an oxy/acetylene or oxy/propane torch. That looks like it has spent about 1 winter in the rust belt.
It's a pain to do rust prevention. (speaking for my self) Just have a pro do it. They' ll remove it and paint it with marine paint. The fluid film is sticky.
