I plan to start using precat lacquer and have read some comments that heating precat can thin the material without resorting to thinners. Overheating apparently also creates some problems downstream. While I am fairly certain my HVLP has sufficient PSI and CFM’s for the job without thinning, I am interested in the experiences of others. Are there other pitfalls to that differ from nitro lacquers?Thanks –

I used a heated system on a production line. It only heated the lacquer to about 100 to110 degrees because heating it further would cause the fast solvents to flash off too fast, resulting in leveling and flow-out problems. The main advantage was consistency; the lacquer behaved the same in different kinds of weather.
If your lacquer is cold, like 40 ot 50 degrees, then warming it gently would help, in my opinion, but it it's 70 degrees or warmer, I wouldn't bother.
