Look at it this way: wether you sandblast it, strip it with paint stripper, wire brush angle grinder method or other it all makes a mess. Done all three and the fastest and cheapest method seems to be aircraft stripper remover, pressure washer, and angle grinder with braided wire brushes flat wheel and cup types. Sandblasting is great for pitted and flaking rust, old paint and crust all combined into one old and messy tractor with more flaking rust and rust than anything else. It's a mess but thorough as long as you ensure all orifices, openings, and any place where fine grit enters is sealed you will be fine. Did a 9N that way with good results and no problems. Cost me a fortune in black beauty medium though and rental time. On my own time, at my own rate, if you can steam clean it first do that. Then apply paint stripper in thick layers in a shady warm place and let it work. Keep it on there. Then have a pressure washer on hand and blast the paint right off. Final removal with a good cup braided wire brush on a 4.5 inch angle grinder. Get into tough spots with old chisels, screw drivers, metal rulers, files, wire brushes and your done. Contact POR15 Company and get their Metal Ready and spray that Zinc Phosphate on (or Ospho brand product too) with a normal window wash spray bottle and you can then take your time before you prime and paint. Buy a gallon of the stuff you won't be sorry.
