Wow, I came so close to putting a laquer clear coat on my paint but then did some research and I'll warn you guys who might be thinking of painting their bike or whatever they are doing.
Lacquers literally "dry" -- the solvent evaporates. For this reason, lacquers will re-dissolve in their original solvent. By comparison, enamels "cure" by chemical reaction. If you apply lacquer thinner to a lacquer paint job, the paint will become a liquid again. Other solvents can have the same effect (ex. gas, oil, etc...). Lacquers also have minimal UV protection. Lacquers are also "hot" when applied and often attack existing enamel paints, even well cured factory paint.
While you can paint over a lacquer paint job, the lacquer would likely be the weak part of the paint job.
So it's a good thing I found this out. Thought I would put this one out to warn other people too
