single stage vs base coat clear

The appearance is better, but I don't think it holds up as well as the old lead based enamels. It depends on which product your referring to also. Single stage synthetic enamel, acrylic enamel, acrylic urethane, or polyurethane. All different , but most mixing systems I have dealt with use the same acrylic bases/toners with the differences being the binder and activator you use. Most are modified acrylics.
