No, I think you need a dual stage that will put out more air, along with at least an 80 gal tank.

Depending on the gun you use, you can make it work.

I have painted with way less compressor than that, but do it with a non HVLP gun. If you have a gun that requires like 14 CFM & 20 PSI, it will probably work.

Which one? The 40716 requires 1/2 that compressor to keep up. That's the gun I have been able to run with my HF 90234 ( discontinued ) compressor which is 10 gallon 5.6 SCFM@90 PSI.

The 66222? ( replacement for 43430 ) takes quite a bit more air.

I'm currently using a 30 gallon/6hp compressor. It will keep up with my Iwata with no problem. With the Finishline lll, it will run a bit more. Using an air hog, like a HF purple - might have some real pain in air flow. The major consideration that many don't look at until it's too late is 'Duty Cycle'. If it's 100%, (60 minutes running/hour) you probably are golden. 50%(30 minutes), it's not so good. Less then 50% - don't bother bringing it home as it's only good to fill tires and maybe run a primer gun while doing a panel or two.

And those Hp numbers - they are 'developed' horsepower. That 6Hp on my compressor - might be at inrush current, first startup, but returns to running Hp once it's in operation 1-3 or so. My little portable Sears 1.5Hp was just that and had a 100% duty cycle - but it diedwouldn't run much of anything but a siphon feed gun and fill tires - kinda)

This is my paint gun.

I use a 3 HP single stage compressor to supply air to it.

But I run air through this extra tank first.

What I do is locate the second tank close to what I am painting. I use the regulator on the air compressor to drop air pressure going into the second tank to about 40 PSI.
When the higher pressure air goes through the regulator, it obviously drops pressure. When you let a gas (air) drop pressure two other things happen. The volume of the gas goes up, and the temperature of the expanding gas cools.
This allows a "too small" compressor to keep up with my HVLP spray gun.

You can paint with one like that with only a couple of problems. It's going to cycle fairly quickly, and quite often. The second issue is...it's a single stage. Recovery time is going to be a little slower, and with that, heat will be one of your big concerns. And you know as well as others do, a single stage compressor generates quite a bit of heat and along with that come moisture. So you'll need to make sure you have a good water trap close to the compressor and also close to the gun. You can get one of the water trap balls that go at the fitting of the gun to trap moisture before it gets into the gun.

Whatever you are painting, when you have a little free time, do a dry run on the vehicle. Just take your gun, hook it up, set the settings at the compressor and adjust the settings at the gun and air paint it. You could also have a buddy in the background playing the air guitar just so you have something to listen to. All kidding aside, air paint it with the correct settings to see the cycle times. How often does it take to start, how long does it run, and are you maintaining good pressure at the gun throughout the cycle times?

Then you can adjust yourself to compensate for what is lacking, where. Instead of shooting the complete topside, you may have to shoot the roof, cycle, shoot the hood and maybe even the trunk before it cycles again. Then either make a mental note for the big day, or even write it down on a whiteboard and hang it up so you remember.

I have a buddy that has completely rebuilt and painted (show quality) a '69 Camaro, a '67 El-Cee, and a '80 Malibu all with a small cheap horizontal pull around compressor. IIRC, it's a cheap Sears model, maybe 20 gallons. He would make a couple of dry runs before he painted and adjusted accordingly.
