Molded in the strangest plastic I ever worked with. The more I sanded, the worse the finish got, as instead of sanding smoothly, the plastic flaked off in layers. I ended up basically brushing on CA, and sanding that smooth.
To add insult to injury, the first decal disintegrated on hitting the water, so a coating of good old MicroScale Decal Film went on.... again disaster struck, as they reacted as if I brushed on SolvaSet! Eventually they settled out, and only had a tiny amount of silvering, which I touched up with a brush and some thinned down paint.
Still have a little more touch ups to do, before it hits a base.
