I dug out these Mantua cars because... I don't know.
They're heavy. NMRA standards at least.
Started off with the water car.
Popped the tanks off, masked them, and hit the inside with flat black. Then I painted the outside flat brown.
Mixed up some water and poured it in. Some leaked at the tank seams, but that's ok. We'll pretend it sloshed out onto the deck of the car. And I toned down the DOT yellow car.
I hit the trucks with some flat clear spray and laid them on a paper towel. Then I dusted the paper towel with some weathering powders and blew the powder onto the still tacky trucks.
My truck tuning tool went on hiatus. When it gets back I'll ream the trucks so they'll be amenable to Kadee wheelsets.
