Painting question

The time is near for color. One thing (like it's only one) I have a question about is this. In between same color coats, do I run cleaner throught the gun and blow it dry? I suspect no, because it might contaminate the next coat.
But I need a definitive answer.
And then along the same lines, what is the best way to clean the gun before shooting the 2nd of the two tone color. Should I just run laquer thinner through thte gun or what?

Any help will be greatly appreciated!

Cleaning the paint cup and paint passage of the gun is all that is needed. Remove cup pour out paint and wash clean, run thinner through the gun. Not dissemble and clean, do not soak the gun either. It is important that the proper cleaner be used, in other words all lacquer is not the same . Talk to the paint dealer where you are buying your paint, he can advise you

In between coats of the same color, you DO NOT need to clean the gun. You should be putting on the next coat of paint in about 15 to 20 minutes depending on the temperature.

between colors and between color and clear...It's a safe call to remove the air cap then the fluid tip and with a Q-tip soaked in thinner swab out the color that will hang behind the fluid tip and lay in wait to ruin the day. Keep at it until the swab comes out with nothing on it.. Sometimes that little bit can semi dry and the later all come out at once when a different reducer in the clear etc.. loosens it and make you cry..

After you put the gun together,shoot filtered clean dry air through untill it appears empty...then wait a few seconds and reshoot just air again and to be sure no thinner has finally drained down and is siting in the same low spot as it too want's to ruin your day. It needs to be all the way dry...Even though your carefull always trigger your gun off and away from the panel once more to clear it before you really commit .

I do the same thing Milo does when changing colours or products and when finished with my gun. One extra step I do is run some reducer behind the thinner. I'll put a couple of ounces in the gun and swish it around and run it through the gun. Over kill, maybye? But when it comes to a paint job your gun can never be too clean.

Cheers!!

I am a greenhorn at these, but I agree and put a few ozs of reducer through my gun and spray some of it in hopes of flushing any residual lacquer thinner before putting my paint in the cup.

Something a LOT of painter miss is unscrewing the CUP off the gun.
I'm amazed at the residue left behind after a THOUROUGH cleaning of the gun as stated above. Pull the cup guy's and SEE what you find left behind in the fitting and cup opening.
You do not need to clean between coats but a color change or going to clear with the same gun can be an issue. Thats why I like a dedicated clear gun, I know what has gone thru it and it's CLEAR.
