Before I begin to ask the full question, I'll give you a little background in relation to the topic. A while ago, back in 2003, I bought myself an airbrush kit. This basic airbrush kit was from Testors, and involved a can of propellant that you attached the airhose to (which is connected to the airgun). Now, I did have some problems, I made some mistakes (like I didn't know that you had to thin down the paint for it to spray) and I could never get the hang of it. So, I figured that using automotive spray paints were better because they went on smooth and dried fast, I put the airbrush kit away, only to never think about it again. I did think about the airbrush kit while I was in film school, as when I discussed it with an indie art supply store customer service rep, she explained that airbrushing with a can of propellant wasn't good because of how you'd end up losing pressure with each press. With that in mind, I decided to file it away.
Well, the week before Christmas, my Dad and I went over to the Goodwill Good Cents store in Tallahassee (we love hitting as many of the Goodwills over there). For those not familiar with it, basically the Good Cents store is a "last chance" store for merchandise that they have an overabundance on or didn't cell at the regular stores at a very discounted price. When I was there, I came across an airbrush compressor. But not just any airbrush compressor, I came across the Testors Model 9169 Air Compressor. I recognized this airbrush compressor not because of the "Testors - 75 Years" sticker on the top, but I remembered seeing a picture of the compressor kit back in 2003, which utilized the same airbrush gun that came with the basic kit I had purchased. So, without knowing if it ran or not, I bought it (only paid about $1.50 for it). After getting home, I plugged it in to test it out, and it worked. I began to wonder if I was right about the connection on the end of the air hose, which I had though would connect. I fished out the old airbrush kit, and pulled the air hose and air gun out. To my surprised, the connection fit. I tested out the compressor and the airgun, both work fine. So, now, I'm beginning to think about airbrushing again, and I know I want to attempt to try it sometime. But, I realize that I really don't know all of the basics.
So, are there any tutorials that any of you guys know that covers the basics of airbrushing (be it a model or a prop)? Which tutorials are the best ones?
