My original thought was that I'd need to sand any rust spots back to bare metal and then spray with something like Rustoleum.
It sounds like there might be some other products out there that advertise an ability to bond to the rust and then seal, preventing the need to sand.
Has anyone used either of these? What works best for you all when touching stuff up after wheeling?
You can use a product like a Rust Converter
to make the surface paintable, then just spray it with some black paint. I would recommend that if you had a few big spots to do, and if the rust was more than a little bit of surface rust.
If you have just some smaller areas, simply sand it off and get a nice bare metal finish. Then get a good black paint or even better, some spray on bedliner and coat the rails with it.
Hope this helps!
