Thread: Gun cleaning

Tweet

Do I have to clean the spray gun between each coat. I ask this because of the flash times. I would believe that if the paint I just sprayed flashes in or dryes in 15 to 45 minutes then what was left over in the gun must be drying also.

No. The paint on the car lost part of it's reducer as it was sprayed through the air, and it is drying fast since it is spread out in a thin layer with the air moving against the surface.

The only thing you would need to worry about is paints that have a hardener mixed in.

On the can, or in a product sheet that comes from the manufacturer, it will give you a time called "pot life". That will tell you roughly how quickly it will start to thicken up in the gun. Usually 1-4 hours, from my experience. My own products are okay for 3-4 hours, but check whenever you start using something new that has hardener included.

If it does start to thicken, clean the gun quickly. You won't be able to spray it anyway, if it is setting up.

JUST TO BE ON THE SAFE SIDE I WOULD POUR A FEW OZ. OF ACETONE IN THERE AND SPRAY IT OUT. IT'LL TAKE 30 SECONDS AND SAVE YOU FROM PICKIN' DRY PAINT OUTTA THE TIP

i aways cleaned the the the cap with thininer and tip
