I thought your weathering of the X31 in coal tar chip service was right on. Somewhere, I found a photo of adingle door car tht had weathered right down to bare rusted metal, with that bluish purple tone on much of the surface. I started an undecorated Bowser model and painted one side in PollyScale, no lettering. Wasn't sure how I would do the lettering later - maybe heavily sanded decals. Anyway, thanks for the cameo on how these cars were used. thanks for
