I second all of the modelers who say they only use enamels; in particular, I've been using MM enamels exclusively (well, except for one or two bottles of MM acryls) for the last 30 years (ever since Pactra stopped making enamels; anyone else remember them?). I agree, enamels tend to go on better than acryls, and they are definitely more durable than acrylics but, unfortunately, Testors dropped about 25% of their enamel line last year after they got bought out by Rustoleum (including Armor Sand, one of my favorites, Pale Green, and SAC Bomber Tan). I contacted Testors/Rustoleum about the colors getting dropped, and they said they still make them, but only in acrylics. So, I guess I'll eventually be using MM Acryls, whether I want to or not!
