Spray Gun Regulator

we have mostly been told by the professionals here to keep a good regulator on the wall and keep that pressure in the line to the gun. I get these regulators all the time with cheap guns, most of the time they are cranked way up and the needle falls to about half of what you set it at after you start spraying.
 
Mitch you using it to regulate gun pressure from an already regulated line? If that's the case it will work ok. They can be restrictive though sometimes. What I do although Barry recommends something different, is when I'm in the booth I set the pressure at the regulator on the wall just in front of the hose. (we use a 35 foot hose in the booth) No regulator at the gun. Your air setup may be different but you could try setting your pressure at the regulator where you connect your hose, provided you have one there. If not you may want to rethink your layout. Primer, and base not as critical, but when you shoot clear having something restrictive can/will affect how your gun sprays the clear.
 
The way Chris describes it is how I was taught. The only time I'll use an in-line regulator is when painting smaller parts (IE: brackets) and that is basically a cheater valve with a gauge.

It's hard to go away from Barry's recommendation for me. I have learned a ton from following this forum, especially Barry's recommendations... do you guys have any reasons as to why you've done it one way or another? Why only small parts? Why is the regulator more restrictive than a hose fitting?

Not trying to be a dick, just trying to understand why certain people do things each way.
