Ian, I am a frustrated wanna be painter too. I figured out early on you really need some kind of spray booth. I made a portable one with PVC pipe and poly tarp that works outside if you have a decent day. That really works better. Ventilation is better, you get real light and you don't "paint" the inside of the house. I made this to shoot poly on my kitchen counter tops and cabinets. It worked great. My next painting project is probably going to be a Harley. Do you have some good guns? You can get a pretty decent "touchup" gun for less than $100 that does great on small projects (about 1-2 spray cans worth) but I wouldn't paint a car with one.
