Will I really get a high gloss finish by putting say 6 very thin coats of lacquer?

Lacquer is unique, as it does not undergo any molecular changes when it cures. It dries by solvent evaporation alone. The reason for applying several thin coats is that the solvents may become trapped, and the paint may appear dry on the surface, but will be wet underneath. Also, piling on heavy coats may result in checking problems. Nitrocellulose lacquer, or acrylic lacquer will dry to a dull shine (satin). It has to be polished to get a good gloss. Fortunately, although lacquer has many drawbacks, it is very easy to work with. Apply it, wait till it dries thoroughly, and polish it.
