There are numerous good web sites to purchase acrylics online as I have, but you may want to check out your local hooby shop first. Some very excellent acrylics many modelers give kudos to are:
1. Polly Scale
(a very good over-all modeling acrylic, that fits the bill for brush painting and airbrushing. Excellent variety of colors matched to FS standards, German WWII, etc..)
2. Tamiya acrylics
(very good acrylic that brushes ok, airbrushes very well. Takes getting used to. Colors are limitted but custom mixing are possible with recipes)
3. Vallejo "Model Color" and "Model Air Colors"
(A relative newcomer, brush paints and airbrushing is top of the line. Large variety of colors-with some matched to FS standards as well)
4. Testors Model Master Acryl
(A very good acrylic with a large color variety as well, like their enamel counterparts. Brush painting is very good, as well as airbrushing. However, balancing thinner, air pressures, and paint came be a chalange for some airbrushing tasks. Takes getting used to.)
5. Gunze Sangyo Acrylics
(A amoung one of the original modeling acrylics, a favorite and more available in Japan-becoming more available in the US. A "Huge" variety of FS, German, British and Russian colors. Airbrushes and brush painting is excellent!)
6. "Xtracrylix" from Hannants of England
(A new kid on the block with a surprisingly large variety of colors matched to FS,Britsh, German, US and Russian colors. Easy to brush and airbrush. Thins with distilled water and alcohol.)
I like to use Tamiya Acrylics to suppliment my huge variety of Model Master enamels.
