We are heating Sherwin Precat Lacquer T77F37 in our spray operation. The temperature we run it at is 110 degrees. Is this too hot?
I did a large job with Guardsman precat lacquer. We were using a finish heater at the time, so we went ahead and used the product like a regular lacquer. After six months, the finish got little cracks in it. Guardsman said that by heating the product, it was made too hard and could not take any stress. I don't know if your product will do the same or not.

What you have to look out for, if you lower the temp, is the temperature falloff from the tip of the gun every 1" from the surface decreases the temperature very rapidly and if you don't have enough heat to start with, you lose any advantage.
