Renner’s,
You may be right about the black enamel wasn’t fully cured under the lacquer. If that’s the case, you can sand out the problem and repeat the process without trying to find a shellac. Allow extra time between the enamel and the lacquer and that should solve the problem. Another trick that works when putting lacquer over another finish, since lacquer burns in as it dries, would be to make sure you spray the first coat or two of lacquer on very lightly. The heavier the coat of lacquer the more time it has to burn into the finish below and in this case may create a blemish. As the coats of lacquer build, it will burn into itself instead of the enamel and you can spray a heavier coat on for the final finish. Hope I didn’t confuse you too much. Let me know if you have any questions.
