Can you repair the finish.
I recently finished a model with an acrylic lacquer top coat. When I went to repair the finish and sprayed on some of the base colour coat it crazed on the edges.
Did you ensure that the area was thoroughly clean ? Did you go over it with alcohol and CLEAN rags prior to painting ?
While you can put enamel over lacquer (not the other way though ), you really should LIGHTLY MIST the first couple of coats on and let dry between coats. Occasionally the enamel and lacquer do react with each other even though can put enamel over lacquer.
Since you are using a lacquer clear coat, I presume all the paint is lacquer. Lacquer does have certain features that are nice, however, for future repairs, etc, I prefer to stay with either enamel or latex for the complete paint job.
What I do is either use ONLY enamel paint OR ONLY latex paint followed with an acrylic enamel clear coat. I have found that doing this, I have had no problems with repairs/painting.
