SAVE SOME POWDER FOR TROUBLESHOOTING

It's January and a new batch of powder paint has sprayed well for several weeks, thus proving itself to be a good powder for color match, electrostatic chargeability, etc. Place a small amount (10 to 50 lb) of this powder into dry storage in the same container in which it was received.

Along comes March and all that wonderful January powder is gone and a new batch of powder just received is now being used. A few days pass and things are not going too well. Both the powder supplier and the equipment people have you going in circles, and convinced you're the problem. In some cases they are right, but you know that it's either the equipment or the powder, but which? Now is your shining hour.

Remember that January powder you put into a very well cleaned powder hopper along with a clean powder hose is a better idea. Now spray January's powder and if the items now being coated look as good as they did in January, then you know your March powder is the problem.
