Thanks to all who have made suggestions.

As for those who say it would be out of scale, I agree that in HO scale much if not all of the characteristic foundry casting texture would not be visible. However, I believe there are situations were some out-of-scale texture is appropriate. How else could we convey the difference between something that is rough and flat (i.e., flat-painted) and something that is smooth and flat? For example, the stucco texture on the side of a building would be all but invisible in HO scale, but if we want to convey "stucco" in HO we have to go out of scale...
But the texture of stucco is 50 to 100 times larger than the surface of a casting. Even though the mold is made of sand, it is as smooth as a plaster wall, and unless part of the sand has broken away during the pour, the surface of the resulting casting is almost as smooth. Stucco, on the other hand, is applied to the wall by slinging it off the trowel, and sometimes adding swirls with a stiff brush.

What says casting to me, more than anything else, is fillets, because foundrymen know that sharp outside corners in a sand mold won't hold up, so every inside corner of the pattern has a fillet applied, often made of wax so it is easy to fit around curves. I personally think the best way to finish an HO scale model of a casting is to paint it with thick, goopy paint that fills all the inside corners, thereby modeling the fillets, then dust the still wet paint with talcum powder to kill the shine and give just a bit of surface texture.

Who remembers Michael Gross's "Model of the Month" stucco-sided Hermosa (?) depot? The texture was way out of scale, but it worked. I think the same can be true for a large foundry casting. Perhaps a physicist could explain it as light and reflection not scaling down well. I don't know. But I'm going to try modeling the foundry texture and if I like it I'll post some photos and you can be the judge.

I stipple on black artists acrylic straight from the tube for this. It can be weathered or toned down after it dries

Krylon has a group of paint colors they call “multicolor textured� that leave a speckled rough surface, almost like fine sandpaper. I bought the tan color yesterday to try on some autumn trees but, I’m sure it has many other applications around my layout. They also have a dark brown in the same line that might work for the “rough casting�look.
Another Krylon product group that I find useful are their “Camouflage Colors; non-reflective nature color�. These paints are dead flat and available in tan, dark brown, dark green and black. I’ve also bled off some of these paints into a smaller container and used them in one of my airbrushes when I needed more control. They work just as well by that method also, especially for model rail cars or vehicles.

I agree with Ron. The 1:35 armor guys do work at getting that "as-cast" look, but in HO scale I don't think you would see it.

Plasticote automobile primer will do this. Spray at about twice the recommended distance, with light coats.

I'm working on a load for one of my HO steam era freight cars. I want it to look like a foundry casting and I seem to recall having read about a spray paint, possibly from Krylon, that will give a sort of rough, gritty texture to what it is sprayed on. Anybody know of such a paint? I'm not talking about the spray-on orange peel coating or the fake spray-on speckled granite paint.

Compare new, unpainted modern coupler heads for an example of non-machined steel surfaces.

Floquil, when used at very high pressure (60 psi instead of the
normal 10 psi) will hit the car dryer than usual and will produce
a nice rough finish. Dave Hussey used this effect beautifully to
simulate a tank car coated with exterior urethane foam insulation.

Richard,

As I can't get to it right now, I'll tell you what I remember.
A product called Faux Fabrix (I think that's spelled right) made
mostly for the model car guys for seat textures is available in black, red and
gray. Small spray can. See if your LHS can order it. Seems that SMP (?) was
the manufacturer.

Krylon has a good selection of rattle cans of interest to model
railroaders, and I found a good selection at Michael's. I wasn't looking
for texture paint, so I didn't pay attention to the details, but a trip
to Michael's is worthwhile for other model projects as well as yours. My
best find so far was the flat aluminum for painting SSS passenger cars
(OK, that's another list, but it's a good example of what you can find
there). I like their flat aluminum better than any metallic model paints
- less grainy, smooth finish, and dries fast. I've used Krylon Crystal
Clear to coat inkjet decals, and I've use Clear Satin when I didn't want
a gloss or flat finish. Testors probably has some texture paints, too,
so check out their web site.
