Once in a while on my way to work I will stop in a local Harbor Freight store and look around for do dads and thing-ga-ma-jigs. I find lots of cheap tools that are just great for my hobby. I found an air brush kit for $20.00. What the heck, I bought it. So I tried it out last night for a primer coat on my Bison. It worked just fine. I would not use this brush for detail work, but for priming and sealing or covering large areas. The kit even included a spare needle. For any beginners, the budget minded check this place out. I found dental picks, file sets, drills, tweezer sets and other goodies cheap.
