Default Fixing minor rust

Hey all; sorry in advance if this has been covered before (I'm still a fairly new member, as my stats show).

What is the best way to repair minor rust spots? My 1969 Pontiac Executive (a first cousin of the Bonneville) has developed some surface rust on the lower rear door & quarter panels from 35 years of water and salt spray. I want to stay on top of the problem, before the rust penetrates any deeper.

I'm interested in knowing what grain(*) of sandpaper to use in removing the rust, and then how to effectively repaint the areas and smooth it out. I'm working with the original paint job, so matching touch-up paint might be an issue. A show-quality finish is not a concern of mine, but I would like something that looks nice and is not immediately noticeable. Thanks in advance!

I'd sand it with something fairy coarse first, probably 320, then work to 400grit. Work at it until the rust is gone. When it'* gone and sanded fairly smooth prime it well, and let dry according to directions, then sand the primer with 600grit. Then apply the color coat according to the directions. Apply clear coat according to directions, then let dry. Sand with 800 grit up to 1500 or 2000 when paint is dry. Then use rubbing compound according to directions, giving the paint enough time to dry, and buff to a shine.
