Welcome to the forums, Patrick! And welcome to the world of airbrushing! What kind of rig did your wife get for you?
I use a Paasche VL, with a Craftsman 1.5 hp compressor and a 3-gallon tank. I got that because I can use it with air-powered tools, as well as with the airbrush. Also, I don't need to worry about noise.
I recommend Tamiya acrylics, they're formulated for airbrushing. I use their proprietary acrylic thinner, myself, but you can also thin them with lacquer thinner and get an absolute dead-flat finish.
I look forward to seeing your builds!
Best regards,
Brad
