Happy Holidays Transformer fans! I have a question about painting Shapeways pieces for the experts in this field. I bought the two pieces shown below from a Shapeways creator named SteamShield; they allow CW Brawl to combine with the Fansproject Colossus set. I wanted to paint them olive green like CW Brawl, and I messaged him about it. He recommended I use the Processed White plastic and spray it with my color of choice, then coat it with a thick layer of primer and sand it to create a smooth finish. I've never done this sort of thing with Shapeways parts before, so I was wondering what you guys recommended. Any brands of paint that are easy for beginners to apply? What kind of primer should I use? Thanks in advance!
