This spring sometime, I'm going to modify mine a bit. I'm going to segregate the blower from the paint booth itself. I'm going to run the hose down through the floor and have the mower completely outside the room in which I paint to eliminate the blower noise.
That way, when I paint, I can actually use my sense of hearing to improve my painting a bit. When I use the Iwata and try to spray very fine mists of paint or try to paint very fine lines, it helps to "listen to the brush" because you can actually hear the paint beginning to be added to the air stream.
Of course, when I'm doing basecoats, I just open up the brush trigger a bit more...and crank up the stereo.
I'll also be adding a few lights to the "window" I installed on the top of the booth. You can't have too much light when painting after dark as I usually do. The extra light allows you to be more accurate when doing detail work and it allows you to make your basecoat fades evenly on both sides of the bait. Light is also a big help when spraying pearl powders, which I do a lot.
I'm also going to add a small work table to the shop. I often use a vice to hold the baits while doing detail work. During the application of details I often place the bait or the vice holding the bait on a soft cloth so that I can approach the bait with the airbrush from above. (I know there are many different ways to do this, but that's the easiest way for me). Since I'm spraying only micro amounts of paint during those applications, the exhausting of fumes and particulate is something that I don't worry about affecting other objects in the room and the respirator handles that tiny bit of overspray nicely. For now, I'm just setting the bait on my chair seat and sort of kneeling next to if. A table next to the booth would probably be a bit easier.
