I just finished 3 IM tanker kits and tried out some Bragdon Weathering Powders I picked up at Springfield. I used an old LL boxcar from the junkbox to experiment on, and it looked so good I put a new roofwalk on and lowered the underframe-looks pretty good.
Next up are some Undec Altlas GP7 shells to assemble to GP20 mechanisms and paint up for the PRR, and some sharks to decoderize.
