Unless you need something very specific, there's little reason to patronize StewMac. They're seriously overpriced, their shipping is expensive, and they have such a mediocre/cookie cutter vibe. There are certain things you just can't get anywhere else, but for the most part, it's just overpriced, generic junk. Congratulations. Nitro and acrylic lacquer are compatible. There is no problem applying either one of them properly over the other. See Fender in the '60s. All of their '60s metallic finishes except for Sherwood Green used acrylic lacquer (Dupont Lucite) color coats with nitrocellulose lacquer (Dupont Duco) clear coats. Olympic White was the only opaque Custom Color that was acrylic color with nitro clear (though there are some non-clear-coated examples, especially earlier in the color's history, as there are non-cleared examples of several Custom Colors, even Lake Placid Blue Metallic). Sherwood Green was the only metallic that used nitro color coats and nitro clear coats. Opaque Custom Colors, and standard sunbursts and blondes, use nitro color and nitro clear (except Olympic White, as mentioned). And all went over the catalyzed varnish sealer/filler Fullerplast from 1963. Acrylic is a type of binder material, while "lacquer" specifies the mechanism by which a finish hardens. Your statement makes about as much sense as, "Paragraph isn't a pencil." Well...sure. Paragraph isn't a pencil, simply for reasons of logical tautology. But a paragraph can be built with a pencil, among other tools. Acrylic isn't lacquer, simply for reasons of logical tautology. But acrylic can be applied in lacquer form, as well as using other methods. In modern parlance, "lacquer" = solvent based finish. I.e. something that is a mixture of a solvent and a binder when wet, and binder only when dry (solvents escape and leave the binder behind after application). Whether it's a "lacquer" or not has little to do with the binder material used. There are even lacquers that use catalytic binders, making them a hybrid of a lacquer and a catalyzed finish -- two descriptors that are traditionally at odds. The solvent carries the catalytic binder onto the surface, then evaporates out, as the catalytic reaction takes place. Even though the binder is catalytic, it's still a lacquer when applied. In other words, of course, "Acrylic isn't lacquer," because the words "acrylic" and "lacquer" describe different things. But "acrylic lacquer" certainly is lacquer...or else it would be called "acrylic [something else]."
