There's nothing wrong with solvent based lacquers except the spray is toxic and you have to wear a mask rated for organic solvents to use them, which many guys don't want to do. As far as water based acrylic paints, Createx is the industry standard in quality. Createx also makes Auto-Air which include some pearls and metallics. I mix and match water based colors from any manufacturer to find the colors I like. I often buy from Wasco, http://www.taxidermy.com/ and like Smith Wildlife paints the best. Createx makes acrylic paints in 2 variants: opaque and "transparent". You can layer colors for more life-like fish effects with transparent colors. But you will still need a few opaque colors for white color basecoating, etc. The Polytranspar Superhide White is the best white basecoat acrylic I've ever used. Most of the taxidermy paints come in only one acrylic variant, most often transparent. Be mindful that most taxidermy paints are stocked in both water based acrylic and solvent based lacquer types, and it's easy to order the wrong type.
