Ever learn a new modeling technique and wished you could go back and re-do something you'd already done? You can!
Some years ago I purchased this nicely detailed Intermountain 40' PRR boxcar. I weathered it following a photograph in a book, building up layers of pastel chalks and Dullcote. I never much cared for how it came out (too splotchy). I tried to mimic the effect of a yard worker wiping the car number at a hump (a common occurance before the advent of the Automated Car Information system). Overall, didn't much like it:
Well, one wonderful thing about Dullcote is that is can be removed with 70% isopropyl alcohol without damaging the underlying finish. I slathered on the alcohol and wiped the car down with a stiff brush, removing most of the weathering and Dullcote. The result is a fine haze that will disappear with a new cote of Dullcote.
Aftr a new coat of Dullcote, I re-weathered the car using washes made of acrylic craft paints, basic windshield washer fluid, and water. One of my favorite techniques is one I learned from Rich Yourstone, and that's the scrapes from the sliding door. If the door opens (as it does in this case), just dab some thick dark rust colored paint on the backside of the door and slide it back and forth.

These closeups also indicate to me that the roofwalk is warped.
