Hello;
What difference is there between Tamiya, Vallejo, Hobby Color acrylics and cheap craft paints? I can use them for airbrushing too, in addition they are not toxic like my Tamiya paints. What makes these brands better than my local art store's acrylics?
Thanks.
Unless you drink them, I wouldn't worry about the toxicity of Tamiya paints, any more than I'd worry about any of the other brands and their formulas.
Having said that, as far as acrylics go, I'm like many of the others in that I have acrylics across many brands, including Tamiya, Andrea, Vallejo, Model Master, and craftstore acrylics (Apple Barrel, I think is the one, and Americana).
The craftstore acrylics have more coarsely-ground pigments, generally speaking, and I don't really airbrush them anymore. But they are excellent for weathering, and when I make groundwork, I use them for coloring the ground. I like using them for such applications, since they're cheaper and can go farther, than the smaller, more expensive paints from other makers.
I've seen others use them, though, on things like painting figures, and get results that were just as good as they would have gotten using more expensive, purpose-made acrylics.
I thin them with water or with isopropyl, depending on what's handy at the moment. When I airbrushed them, I used isopropyl.
What makes the other brands better than craft store acrylics? Well, generally speaking, they're made specifically for scale modeling and for painting figures. They generally have very finely ground pigments, which impacts the way the paint looks when it dries and cures. And Tamiya's paints were formulated for airbrushing, and are meant to be thinned. Once I learned that, and learned that they thin best using Tamiya's proprietary acrylic thinner, I started getting consistently good results with their paint, whether applied by airbrush or by hand.
Hope that all helps!
Best regards,
Brad
