I saw a couple of videos on Youtube about mixing mica powders with clear and airbrushing them. It looks like an economical way to get a whole bunch of cool metallic colors relatively cheaply. I did some research on Amazon and found a 63 color box of 10g each mica powders for $40. I also found a quart can of clear lacquer for $20. Today, I tried out a few of the colors with a rudimentary mixing ratio of 1/8 teaspoon of powder to 2ml of Mr Color Leveling thinner and 2ml of the relatively thick clear. The superfine powders mix with the thinner pretty well and then the clear was added. I shot it through a 0.5mm airbrush at 20 psi. It lays down like a typical tinted clear whereas you keep adding layers until the color is where you want it. It is very tolerant of running if you wait 15-20 seconds between applications of 6-7 passes. You can go heavier towards the end. When you are done, it looks really glossy. It dries in a couple of hours to a satin to semigloss sheen. I am sure with experimentation of ratios or technique, the gloss could be manipulated. As is, the sheen would be perfect to simulate a vinyl interior. Overall most colors that I tried look like 1/25 scale factory metallics. The few that have larger flecks in them have the "bass boat" look to them. The one pearl I tried really has a pearl effect with pink highlights and a light green aura. It just does not show in the pics. The other reason I got the mica powders was to try it as flocking for carpet. I have yet to do that. $60 for almost a lifetime of metallic paint colors is not a bad deal.
