Max- that piece in the center is upside down. The little "lip" should point up.
I think the LIRR did have B60b cars. The PRRPro Yahoo group has photos of them ( I think).
I had no trouble with painting my HGM resin. In fact, the only time I ever had issues painting resin was with the GHQ L1 tender. I could not get the paint to stick to it and I cleaned it with all the suggested things. I may have been spraying the paint too dry, but I didn't spray it any drier than anything else and never had problems before.
As for the color? I don't know. The right answer is "get an airbrush and mix it yourself" but that's an investment. I know tuscan changed through the years, I think Doug Nelson uses a boxcar red?
I use a 50/50 mix of zinc chromate and boxcar red.
Here's a lousy comparison shot:
The top is Kato, the middle is my mix, the bottom is MTL. The RTR cars are glossy so my mix looks lighter.
