Weathering of Budd RDC

Did someone weather a Budd RDC or knows of a web site with samples? I’ve just got the H0 Modell from Proto 1000.

I expect some very light weathering just removing the high gloss touch. May be the truck are more serious weathered.

The exhaust vents on top could give the roof a bit of carbon build up.

Here are a few photos for you:

I’ve seen photos of RDCs that were completely covered in grime. Dented-up stainless-steel seems to be pretty common too.

The RDC’s on CNJ had so much exhaust stains on it that the roofs almost looked like they were supposed to be black.
