a 60-70 year old tractor that has spent its life outside is very rusty.The entire underside of my car is black tractor enamel. Why tractor enamel you say? Go look at old Massey, International, Ford, etc. tractors from 60-70 years ago that have been sitting outside and in leaky barns.
Not around here and I’m in the heart of the rust belt. Maybe some surface rust but I’ve driven many old tractors that still had their original paint jobs with maybe some patchy surface rust at worst. Ford and Massey both hold up particularly well. Tractor enamel is darn near bulletproof.a 60-70 year old tractor that has spent its life outside is very rusty.
