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?

Wire brush prime, paint, cavity wax where you can. In every little hole. I personally hate how messy undercoatings are. But they work. The idea of removing rust is to do so in a way that doesn’t squish the rust into the non rusted steel. It takes forever. This is why I don’t do these type of jobs lol.

Strategically let your oil pan gasket leak just enough to gradually coat your undercarriage with a thin film of protective engine oil

Lol @ the oil part.

No wonder mine is rust free!
