IMHO, it depends on the painter behind the gun. I agree with Roger about his choices. Tiger Woods can break a stick off of a tree and kick your butt at golf. All depends on who is behind the stick.
Find a gun you can afford and just practice and play with it.

I like my Iwata LPH400 but I also like my Sata, just depends on what you want to shoot. Even some of the generic guns will do a good job, just make sure you match the air demands of the gun with the compressor.

I just got the Devilbiss GTI Plus gravity feed gun last spring and love how well it sprays clearcoat. After I reshot my rockers, the clear put down so well I decided there was no need to sand and buff.

the painter at my work uses a sata for base and the iwatalph400 for clear
i am opainting my dad's skylark and used a satajet3000 for both base and clear. when i first started using it , it came out with some orange peel but once i got comfortable with the gun it came out just as good as the iwata.
like bigblocktank said, you could have the best spray gun in the world but if it isn't used right it will come out worse than a cheapo gun

Sounds good, I have a old model 7 Binks gun. Thought by now the old suction guns (botton can) could not compete with the gravity feed (top can). I was thinking about making it a primer gun.

Devilbiss equipment.
I started painting over 50 years ago and at that time there were only Devilbiss and Binks spray equipment and I started with Devilbiss. I have two MBC cup guns and one MBC converted to a pressure setup with a half gallon pressure pot. These guns are very expensive but last forever and always work very well. You can convert these guns to do anything you want to do by changing the needle valve, air head and cap. These guns are still being used after all these years as you can still buy replacement parts for them. Thank god I am retired and only work on my own cars and a few relatives and friends. Ask any pro painter and he will tell you it is a tough way to make a living. Just my thoughts. Have a great day and happy new year to all my C-4 friends. Allentown Ernie.

John, your question may be a bit misleading but you should have inlet pressure at the gun of 30lbs which should put about probably 8 to 10 lbs at the cap. What I do is run a high line pressure off my regulator (100+) and then I have a separate regulator and gauge at the inlet to my gun. I can play with these settings at the inlet to change my cap pressure. If you do not cheat the pressure at the gun then you will need to regulate from your wall regulator which with line drop can be pretty much like throwing darts unless you have it down to a science. The GTI is a nice gun although it sucks a bit more air than the Plus. If you have enough CFM they spray great-Jim

I think Jim explained it well, 100 psi from the wall to the regulator at the gun which is set to around 30ish to obtain 10 at the nozzle. BTW, the SPI website has some tips for setting your gun.
Good Luck with the project.

John, the simple answer is it makes a huge difference and there is no advantage to running to running full line pressure to the gun. I have three different Devilbiss gravity feed guns (GTI, Plus, JGA) and all three are set differently with gun inlet pressure, slight but very noticeable if you want quality results. A gun regulator is very reasonable pricewise and two of my gravity guns came with a devilbiss regulator, I am surprised yours did not. If you do not regulate at the gun then as you use your supply of air your gun pressure (and air cap pressure too) will vary and depending on your equipment and how large an area you are spraying can vary considerably. Paint is expensive and mistakes are extremely expensive. Get a gun regulator and set your gun at 20lbs and paint a test panel, then 25, then 30, then 35. Each setting will change the air at the cap and change how the paint is being applied. The more you learn the characteristics of your gun the better you will get and you will see firsthand why the gun regulator is a must.-Jim

Is this GTI a HVLP gun?? I've never painted with one. I got Sharpe and DeVillbiss for 33 years. I know I've never seen a gun that required 100 psi, conventional gun any way. That much pressure will blow the damn seals out. Scott, no offense, are you a professional painter every day?

with most of this. Jim, you're pretty good. You do need to have a pressure gauge/regulator AT THE GUN. The pressure drops from the "wall" regulator "X" pounds for every foot of hose you have. X depends on the inside diameter of the hose. With a gauge/regulator at the gun, you've got no guessing. I've sprayed 1,000's of gallons of paint in my life. Yes 1,000's of gallons. Paint just 1 B-52 and tell me how many gallons of paintit takes, good Lord. It takes 20 gals. to just stencil and put markings on. Oh man, i gotta forget them old days.
