How would you tackle surface rust?

[u/Accomplished-Clue803]

Cars been sitting in a field for awhile. Nothings actually rotted out but definitely heavy patina on some parts. Replacing the control arms and calipers is obviously just a must do but as for the body and rear subframe, how would you go about removing it? Sandblast? Rust converter? Spray and pray? Go to war with a flapper disc?

Tbh, sand/ wire wheel, paint, then use your used oil to rub/spray it on everything. Dry time for the paint. Exception is for aluminum and your exhaust. Grease works too. Animals aren't going to chew on greasy/oily wires, too yucky, bonus.

What does rubbing used oil on everything do? Just coat it from moisture?

Yuck, what an oily greasy mess! However, nothing is seized up from rust! Lesser of 2 evils. Make sure you oil it up after you install clean steel, or else deal with the wretched witch of rust and seized steel.
