Hi there according to what I have been told and learned the hard way, Acrylic can go over age hardened Cellulose but cellulose cannot be used over acrylic without some form of barrier coat product which must not be rubbed through! you may not seem to get a reaction at first but I have experienced Crazing and Cracking of the finished job. It took a complete strip to the beguining and bare metal before it could be remedied. Also allow at least 24 hours between primers and top coats plus lacquers or you could get blistering of the finish due to insufficient drying time and evaporation of the solvents.
