if you didn't let that lacquer cure completely (can take up to 30 days) then there is your problem,
I am inclined to agree with that. I have never used ''Paint'' of any sort as the mold surface. I always us an epoxy gelcoat. I make the gelcoat from the resin and graphite powder. The result is a hard glossy surface.

I have used catalyzed automotive paints with good results. I have used spray can enamel and lacquer, each only once, and each with disastrous results.
