From what I've been reading up on that particular brand, it appears they're basically an arts and crafts paint. No one here uses such a brand at all...
I must respectfully disagree with that statement. There are many modelers who use craft store acrylics. If you do a search of the forum on "Americana", "Apple Barrel", and "Folk Art", I expect you'll find posts describing their use.
The advantages of the craft store acrylics are that they can be thinned with water, have no fumes, can be applied by hand or airbrushed, and that they are cheap for the per-unit price. I use them for weathering, and I've started using them alongside my Andrea and Vallejo acrylics, to paint figures.
Now, there is a disadvantage, and that is that they are craft paints, as you noted. Their pigments are not ground as finely as those in Andrea or Vallejo paints, or other paints made specifically for scale modelers. I found that out myself, when I used a craft store acrylic for the underside color on an airplane. The paint went on well, but the finish was rough, because of the coarser pigments. However, I've had discussions with other modelers who have said that they didn't notice that effect. I haven't tried to work around it yet, but I suspect that I might be able to mix a batch and let it settle a little before applying it.
