I bought a few of the Shapeways, 1/144th scale BMP-1s, which are very nice prints by the way, and superb digital sculpts, but on the rear sides, there is some "stair-stepping", instead of a smooth slope, which I want to fill in.
I plan on using a thin coat of primer all over the models, before painting, so as not to lose any details, but need a thicker, gap-filling, primer for the small areas where the "stair-stepping" striations on the model occur.
Any ideas on what to use for that?
What is also very interesting is that the front upper and lower hull glacis both seem to be very smooth, and don't suffer from this, so I'm not really sure why it is as prevalent as it is near the rear hull hatches.
