I doubt any lacquer would take upwards of a week to dry, it's just not chemically engineered to do so. Of course, if there is a lot of retarder in it as you mention or otherwise has clear coat pigments blended into the lacquer recipe, that's another story. Hard clear coats take much longer to cure than straight lacquer.
Lacquer doesn't cure it dries. Not only that but if it dries till it cracks and flakes. That takes a number of years depending on the amount of retarder and plasticisers. The plasticisers are usually an oil that also dries out over time.
SP,
I realize there is no curing with respect to lacquer. That's why I mentioned that one could see it dry in real time. Very high VOC content. My reference to curing was with respect to the clear coat ingredients mixed in with lacquer in certain rattle can paints such as Lustrekote. Lustrekote does require time to, first dry (the pigments are acrylic lacquer based), and then cure (the CC is not lacquer). How exactly this paint is formulated is a bit of a mystery (there is no information on the TF site, a little on Tower's site) but I know it requires time to cure.
There was some confusion regarding my use of the word
leak. Your use of the word
powder is probably more appropriate.
David.
According to tower the CC is a lacquer.

The clear coat may have more retarder than the pigmented paints.The faster drying solvents dry first, once it is touch dry it takes much longerto dry enough to sand. Ihave addedenough retarders to make it take aday before you can sand,but it didn't blush! Acrylic plastic is the same plastic used in pexiglass and lacquer paints are basically this plastic disolved with solvents. The pigments are colored compounds, many of the same ones are used in all paints.
