Preparing the castings for paint

I am getting ready to start prepping my 1950 farmall h for paint and I was wondering what kind of prep work needs to be done on the castings. I don't want to sand blast it. And hand sanding will remove the rough texture. And I was told using acid can hurt new paint if I don't get it fully removed. This is the first tractor I have done. Thanks for any help
 
I use a wire wheel on a an electric grinder, a small wire knob on a small air tool and then some small hand sanding. You will be surprised how much you can get removed with a variety of sizes and shapes of wire wheels.

here is my F12, and that is how I removed all the paint from what you see. I remove bolts one at a time and grind the paint off where bolt is.

When I did my "H" about all I did was various selections of wire-brushs in electric drill, it"s about all you can do. However I did some places use an abrasive grinder wheel in angle-grinder, and altho it removed some roughness, that looked just fine. It was smoother, and not objectionable at all. I relly wouldn"t worry too much aboutit, if you get all the rust, you"ll nevernotice.
 
+1 on what has been already posted. I would add two things. One being you do NOT need to fret and worry about removing 100% of the existing paint from the castings. While I do not advocate half arsed prep work it is just plain a waste of time, money and effort to remove 100% of the paint from the castings. If you want to do it fine but it does not add to the integrity of the job. Number two is where ever the castings are oil soaked such as around drain plugs, gaskets or any other leaks you need to be certain to get rid of all the oil. The test for those places is a spray can of brake cleaner. If you get dark run off you aren't done yet.
 
Thanks for the info. Can the rust be completely removed with a wire wheel or do I need to use something different to get all of the rust off?
