|Shapeways' own material render|
(enhanced for contrast)
The surface can be polished, using steel burnishing tools, to mitigate this granularity somewhat. It doesn't get rid of it entirely though. Shapeways can do this themselves, but they do it by tumbling the item with little plastic balls, which (of course) pummel out not only the surface granularity, but also any small raised details, so it's no good for my purposes.

Battlefront's 15mm Rolls Royce
I suspect that the material would be fine for wargaming pieces, but it's certainly not fine enough for general scale modeling purposes.
