air brush overspray

[tommyb]

I'm new at airbrushing. My question is how do I airbrush over a painted surface (metal) and deal with the overspray, especially spraying on multiple colors?

Air brush overspray is usually very fine. You can get the dry dust out with a tack cloth. You can also use a degreaser to wipe the surface. Be careful that it's not too powerful that it does not disolve the basecoat you just applied. I like PPG's DX330, it's pretty safe and does a good job...

Airbrush over-spray is a little hard to control. The closer you are to the surface the lesser the overspray. It depends on the effect you are going after too. I use a VR3 for my airbrush work. Make sure the paint is thin enough. The thicker the paint the harder to spray. This causes you to pull back on the trigger even more to get it to flow out. You just have to watch for runs with the thinner paint. Using a stencil freehand from the surface is a good way to control the overspray. Let the overspray hit the stencil not the surface.
