This trick helps the quality of spray for ANY spray can style paint.

Shake the can vigorously for several minutes !!!

Next place the can in a bowl of hot, out of the tap, water. The water should be hot to the touch but not scalding. It only needs to sit in the water for a minute or so. The paint will spray so nicely you'd swear you were using a spray gun.

If you don't feel comfortable putting a can of paint in hot water you could also place the can on a heat register while the furnace is running. The whole idea is to give the can a bit more internal pressure. But remember to shake the can for several minutes before spraying no matter what. Lord knows how long it's been sitting on a shelve or in a box before you bought it.
