Update after painting and decals...
I experimented with the AlcladII stainless color to see if I could lighten it up a bit. The stainless over the gloss black base coat looks amazing on small smooth parts, but it's very dark. Too dark for a whole car I thought.
So I re-primed the steel with a gloss gray base coat
As expected, the porous fluting looks kind of meh, not great. From 6 feet it looks OK, but it's way too rough up close for a good shine and it really affects the car's look.
But I've got 4 more cars to do, so I'm OK with this one being the guinea pig.
Also, I primed this car in my old paint "Booth" which was nothing more than a cardboard box. After shooting a whole car with laquer, it became obvious that wasn't going to work. So I rigged up a redneck paint Booth with a ceiling vent that goes outside. The plastic tub makes way less dust, too. You can really see the dust in my car from the cardboard shedding.
The decals went on easy enough, and I sealed with two coats of Alclad Clear Light Sheen.
Also painted the trucks a flat gray... They look way better this way. The details really pop (and it's closer to prototype anyway).
Still have to finish painting the doors and waiting for my green light gels for my windows (I wanted the green tint like the prototype cars had). For now, I just smeared a green Sharpie over the existing plastic and it looks passable.
I'm not winning any contests with this one, but I'm stoked to have a much more prototypical BNSF silver Metra car in my fleet, and can't wait to finish the next 4!
I also included a couple photos of the original Amtrak paint scheme to see a before and after.
