lacquer is the one coat you want to make sure sets properly before you do anything. if the previous coat of paint is tacky before you put another coat on, its not too much of a problem, bt lacquer can ruin the whole job if you dont let it set properly.
I refurbed my misses mini cooper s wheels, an it took me 2 days, an another 2 days on top jus to wait for the lacquer to dry and they were baked in the conservatory lol
