...What kind of paint that North american modelers use?
I use a Paasche VL, double-action, siphon-feed brush. I use both acrylic and enamels in my airbrush.
With enamels, I use either mineral spirits or lacquer thinner to thin the paint, depending on what I have handy.
With acrylics, it depends on the brand. When I use Tamiya acrylics, which make up a large part of my paint box, I use Tamiya's own proprietary thinner. I found that I get the best results that way; I have found that other thinners you might use with acrylics, such as isopropyl or water, do not thin the paint effectively, but give me clumps of paint. I also use lacquer thinner with Tamiya's acrylics sometimes. This produces an absolute dead-flat matte finish.
With other brands of acrylics, from makers like Andrea and Vallejo, to the craft store brands, I find that water or isopropyl work well for thinning.
When I clean the brush between courses of paint, I'll use the thinner I used for the particular paint. When I break the airbrush down at the end of a session, I use lacquer thinner to clean it, and then I let the parts air-dry, unassembled, till the next painting session.
Hope that helps, droog!
Best regards,
