Interesting question. Big time judgement call.
I purchased a soda blaster for rust removal, after reading many different things about it. I preferred soda to sand in the cheaper versions. Turns out, most of my rust, after putting together the new soda blaster, was removed fine from my M109A3 with two different style wire wheels. It's not at all difficult, and believe me, I am no professional. In any case, I got 99% of the rust off, painted with Rapco 383 replacement spray cans first, then rolled the paint on the box with a roller. Yes, a roller. After than, I covered with spray paint again to camo. No museum quality paint jobs for me, but the truck looks so much better and I feel good about removing the rust and getting down to the metal with ease ( or I should say, with a high speed drill). I'm into preservation rather than restoration for lack of skills and an area to work it in. We all have different goals, thus the comment above, "judgement call".
Unless you have more than just surface rust, you should not have any problem getting it off quickly with just a wire brush on a drill. Good luck on your project, and send pics of your work.
