Not sure if this question should be here or in the Paint section. I some of my front suspension torn down and am about to start to remove the rust from the spindle, lower arm, and upper arm. Is there a chemical I can use to aid in this or will good old elbow grease work? I have wire brushes and a paint removal wheel for my arc grinder (not sure if I will use this or not).

Also, once the rust is removed, I have some black satin Rustoleum paint that I want to paint the arms with to protect them from the elements. Do I need to prep the surface somehow or put on some primer? Or will it be fine if I spray the paint on after making sure the surface is clean?

Whatever you do, you need to make sure that the parts are as clean as possible. I actually disassembled everything, and I actually had the parts you mentioned powder coated. For the parts I did not powder coat, I cleaned them with a degreaser, wiped down with alcohol to remove any residual grime (and removed any dried degreaser), primed and then painted. I have a cabinet blaster, and that helped in getting a good prep job, and "bite" for the primer. Even though powder coating is more expensive, I basically never have to worry about them in the future. Either way, the best eay to make sure the paint stays is in the prep.

If you don't want to bother with all of the prep, and show car quality time/effort, the POR 15 Top Coat rattle can works very well, and even lasts for a couple of winter's worth of salt soup.

So far I am using a wire brush bit on my power drill to remove the rust. When I get the rust removed (for the most part), it goes down to where the arms are black but in other areas it is down to the bare metal. Should I completely remove the black material or just enough to just get the rust off before I paint over the arms?

As long as you get the rust off and the surface is scuffed, you'll be fine.
