Heres a photo of one of my models painted. It was printed in WSF, I sanded it verly slightly with 220grit paper and primed and painted it with acrylic "art" paints ( as opposed to "model" paint)
Paint job isnt that great, been a long time since I painted something this small.
Most of the painting is two thin coats, its much easier to get an even coverage that way - and you get two chances to clean up the edges of each colour which is handy if you're out of practice with small brushes.
