Help with stubborn rust! (I hate road salt)

If you live in WV, you know how much they love to salt the roads..
Anyways..

I got my sliders put on before the winter, I threw on a coat of primer and two coats of flat black, it was too cold for me to find time to do more as it took the paint so long to dry, and between coats I'd have to go over and clean everything up again.

Now the weather is decent and I have some more free time I decided to go under and check out everything, and to my dismay it's rusted.. bad.

I just hit it a wire brush and it didn't do shit. I sprayed it with WD-40 and hit it again and it didn't do shit. Steel wool ain't doing shit. The rust is pretty bad and I have no idea how I'm going to get all of it off so I can get some good coats of paint on it.

How do you get rid of stubborn rust somewhat easily, and cheaply (under $50) I don't care to spend a couple hours on each side, I just know if I use what I got now it'll take 6+ hours a side.

Oh, and search didn't help me find a good thread.

 

Any sandblasters in your area?

 

Usually a wire brush and sand paper work for me... Maybe an angle grinder with a wire wheel will speed up the process for you.

 

never thought of that, I'll look into it

 

we haven't had any salt this year! lol

 

I saw a truck salting the roads last week before it was even snowing.

 

How about spraying with that shit that turns rust back to metal and is primer all in one?......after the grinder/wire wheel action.

This kinda stuff.....
