Very informative. I wish I would have seen it before I painted my truck. I was reading the regulator without pulling the trigger. Guess that's why I got so much texture in my paint.

@Micawbr

Not pulling the trigger during inlet air adjustments is a typical mistake that a LOT of people make. If you have questions be sure to visit our forums.

I'm a SATA/GEO/IWATA daily user in the automotive refinishing craft for the past 24 years. I never liked Devillbis. They're heavy, cheap made and don't last like SATAS.

But then again, you don't need high end guns to paint a dog house.

@lapwiz Satas and Iwatas are excellent gun but the guns and their parts are very expensive. These are definitely the guns of choice for people that paint on a daily basis but are also definitely overkill for the person who paint one or two cars per year when they can get identical results using a DeVilbiss gun. When you need parts for a Sata (like a fluid tip kit) you could go out and purchase a good DeVilbiss gun for the price of the Sata parts.

Why would you want to adjust your fluids dial all the way back?

It is simpler to close it all the way then open 4 full turns for basecoat, wet on wet sealers, and adhesion promoters. You should use an HVLP 1.2 set to 26lbs. for those coatings. Ideally, you should have dedicated guns for each product, if you're a pro, I do.

Next, your clear coat gun should be an LVP or RP 1.3 set to 3 to 3&1/2 turns of fluids and 29 to a MAX of 30 lbs of pressure.

That is the simple way to go.

@lapwiz These adjustment methods may work for YOUR spray gun but not with others. The methods shown on our video will work with ALL GUNs that are engineered to be adjusted using the same type of engineering.

@autobodybasics

When you did that, you pulled the trigger ALL THE WAY. What if you have paint in the cup already? I always thought you just pull it the first notch on the trigger where paint doesn't come out?

@lapwiz The reason I ask is because 4 turns out on my DB allows the trigger all the way back, and 3 turns allows it most of the way back, with a separation of about 3-4 mm between the trigger and the base of the gun.

@lapwiz Does this apply for ANY spray gun i.e a devilbiss?

[Zlyzer]

@lapwiz If you think about it, heavy should = quality. Anyway, which ones in particular? I just got hold of an old suction feed Devilbiss GTI that has some good use on it.. the paint has faded where the hand would go and it dates back from 2005..
