RE: What does weathering for us....
I'm a weather-holic.
I can't help myself, for some reason I feel the need to alter whatever surface in some fashion. I'm not much of an AC builder, but even when I do, I have to dirty them up in some fashion. And that's not even finished, I'll need to add the trails from the MGs, the oil staining after the cowl and then the mud spray on the undercarriage.
