I've customised a few figures, and I've found that priming my figures before painting them is deifinitely the next step for improving the quality of my customs. As a result, I've bought an airbrush and I already have an assortment of tamiya paints. I was hoping this thread could tell me what thin (preferably cheap) primers/thinners for an airbrush are out there. Would just a base coat of any solid colour work as a prime coat? Also, what kind of thinner should I be using with tamiya acrylics? Lastly, what sort of paint booth setup do you guys use? What would you recommend? Anything helps guys, thanks.
