Not to go against what other people are saying, but I do it all of the time. I've used chaos black, skull white, tamiya paint, vallejo game color primer (really good). I just thin with some windex (or tamiya thinner in the case of that paint) and there ya go. I also varnish with my airbrushes. I can do it inside, and in the winter.
A great trick is to print black, and then from around a 45 degree angle dust white paint to give you a nice idea of highlights and shade.
Rattlecan primer will always stick better, but if you varnish then you'll be okay. You might notice a difference if you handle the mini a lot while you paint, but I atach to a handle so that isn't an issue.
Cheers
