This is my third paint job.I have only used single stage but my last 2 jobs cameout nice.I am painting a '72 Chevelle using DuPont ChromaOne system.The color is the factory metalic blue.The Base is Chroma base with 7175S activator,the clear is ChromaClear 7900S w/ 7985S activator.I want to use my Sata minijet (1.0) to paint my jambs and under the hood -what shoud my gun pressure be??I will be using a Sata Nr2000(1.4) what should my gun pressure be??The guy at the paintstore says most painters turn the pressure up to 40 to 45 psi so the paint will atomize better???I would appreciate all suggestions and HELP!!!
I bought Lens video a couple of years ago and along with this forum I have learned a tremenous amount!!!Here are a couple of pics of my last job using Dupont SS Chroma.

for the base, looking at 28-30 psi. for clear, go with 40 even. i spray clear with the fluid needle out 5 turns, start with 2.5 turns out and open it up more if you can without running it.

my advise for the minijet, is to leave it alone and use the big gun. thats just my preference though
I believe that the recommended PSI is carved into the handle of both guns. The MiniJet is ok for the jams but it's too small for the underside of the hood. The 2000 would be a better choice.

I haven't sprayed Dupont paint in at least 10 years. The paint store that handled Dupont dropped that line about 10 years ago and no one else locally handles that brand of paint. Around me locally it either PPG or nothing (which is fine because PPG is good paint, along with most of their Omni line).
What I was getting at is not being familiar with the paints you're shooting I can't be much help to you on this one. Some general points of advice that might help is make sure the car sheetmetal is warm to the touch and equally critical is that the clearcoat also be warm (not cold after sitting in a cool garage all night). Clearcoat thickens up as the temperature goes down. Cool or cold clearcoat will not atomize correctly even with a $500 Sata. You'll get excessive orange peel and and runs if the clear is cool or cold. If you're going to spray the jambs, under the hood and trunk at the same time as the outside of the car then I agree to just stick with the big gun instead of screwing around with two different guns. I just did a '72 ElCamino about a year ago and the bottom side of the hood was black from the factory (not painted the same color as the outside of the car). The only thing painted exterior color under the hood was fenders inner edges. The cowel and the core support area and under hood were factory satin black.
