I recently finished this Q-Modeling MARS SNOOPER upscale. I used Tamyia rattle can Metallic Red, Metallic Black and Gloss Aluminium for the finish, sealed with Tamyia Clearcoat. Metallic paints are very unforgiving in terms of surface imperfections, so there was a LOT of filling, sanding, priming and filling.
Q Modeling kits are amazingly well engineered and are definitely some of the best kits out there. I can't recommend them hightly enough. I'll post more close-ups later.
