India ink weathering

[rrinker]

Referring to Lance Mindheim's drop of india ink in a bottle of alcohol general weathering solution - would this also work on locos and cars to just generally tone down the shine? Not goign for the superdetailed dirt here, mud here, rust there, grease down here weathering, just somethign to kill the shine a bit and also have that basic overall 'washed down the sides' look. Anyone tried it on rolling stock, or just structures?
