The green one looks too much like mud. You're not just going to get an even coating like that. Rust causes pitting, and usually in clusters.
Fan of late and early Conrail... also 40s-50s PRR, 70s ATSF, BN and SP, 70s-80s eastern CN, pre-merger-era UP, heavy electric operations in general, dieselized narrow gauge, era 3/4 DB and DR, EFVM and Brazilian railroads in general... too many to list!
