Youshould have waited at least 2 weeks before sealing the latex with anything. It takes 30 days for a full cure with latex, even longer if the humidity is high and if you used a brush instead of spraying. I use a heat gun in between coats and then I leave the parts out in the sun for a week to help. Laquer is not very fuel proof and it also needs sufficent time to cure. You may want to strip all he paint off and start over. Sorry to say it.
