I have a cheap airbrush that I could not get to steadily spray a light line. It will start and then just stop flowing paint. I stop and try again and as I pull back the trigger I suddenly get a big shot of paint. I tried thinning and changing my air pressure but it will either stop spraying paint (just air) and then bam! Big blob
So I bought a bran new Iwata eclips yesterday and the same thing is happening??? I’m trying to pre shade but it’s just a mess. What am I doing wrong?
The compressor is just a cheap one from harbor freight but it works and is steady. The primer is Stynylrez.
Try thinner alone through it and see how the control works. Then try thinning your paint until it work right for you.

Thanks. I’ll try thinning it again.
I always run some thinner alone through the A/B before I spray paint. I think it helps.
Bill
Don’t get frustrated. A/B’s are tempermental creatures.

Sounds like your paint may be to thick. Or your pressure is too high. With the gravity feed you should be able to spray at 10-15 psi
Does your compressor have a tank and/or water trap? moisture might be a problem, same problem with two brushes seems to not point at the brushes.
Mick.
That’s not going to work with Stynylrez.
20-25 PSI and doesn’t need thinning. .4mm nozzle or bigger.
No tank, but I have two moisture traps on it. One at the compressor and one on the airbrush. I do not have an accurate way to monitor my psi. I just have a quick detach with a valve on it.
I didn’t think the Stynylrez needed thinning either. I did thin it though and “maybe” it sprayed a little better but would still stop and eventually shoot out a big bunch of paint at once.
I have no idea what size needle it has. Whatever comes stock on the Eclipse HP-CS I guess?
The HP-CS ships with a .35mm needle/nozzle/tip. It’s a little smaller than Badger recommends for Stynylrez, but I think it would work. I’ve not sprayed Stynylrez through anything smaller than .5mm, so I can’t say for sure.
What did you thin the Stynylrez with? Did you try it un-thinned, straight-up too?
You might want to consider adding pressure gage to your setup. It more of a bother finding the proper fittings and what not than it is an expense to be worried about.
Do you have a way to regulate the pressure coming from the compressor?
I have a pressure gage but not a regulator. There is a micro valve on my quick detach coupling but that’s it.
Ive only sprayed the primer unthinned till today. This is the first time I’ve tried to paint any details and haven’t noticed issues till today. For thinner I have Createx Colors 4012 water based reducer.
I was looking for a pressure regulator yesterday but wasn’t able to find one smaller than 1/4" and I coudnt find a reducer for it. I plan on just buying a good compressor here soon. Probably on the first One that has a tank and a pressure regulator on it.
Take a look at the fortress line at HF. Quiet, plenty of pressure and an output regulator. Has 1/4" qd’s. My 2gal was about $165, and will do other jobs as well since it’s 135 psi.
I’d put on one of the red “pumpkin” water traps, and a fine adjustment regulator.
You can find brass adapters for 1/4 npt to most anything at a Napa or other auto parts store
I may do that on Monday
Have you strained the paint? there might be lumps in the primer??
Also what PSI are you spraying at?
Beat me to it, I’m curious too.
Not an AB expert but could water still be getting through the traps? Have you opened the valve at the bottom to drain it lately? I had the same problem awhile back. Besides a good AB cleaning I got nothing.
If you use a compressor for other things, I agree with Goldhammer. I saw him mention the Fortress Ultra Quiet and bought it for 135$ on sale. Love it! Super quiet and my fillings aren’t loose like after using my HF 3 gallon.(it leaked like a sieve but had a good life for a 30$ air compressor)
I’m replacing the compressor first. No moisture in it at all but it’s an old piece of garbage I’ve had around for years. I have a 225 gallon compressor I use for my impacts and spray guns but it’s in the garage.
I’m probably gonna get that same compressor on Monday. Then on the first I’m buying a Paasche Talon to try out. I’m sure the problem lies somewhere between the compressor and my skills so I’m just going to fix everything in between and then work on my skills in using it all. That way it’s all I have to worry with.
I set mine up with a qd at the ab to ab hose (NEO).
The compressor end starts with the pumpkin trap on the hose, and then a regulator with gauge, and then a 1/4 qd that plugs into the compressor. I’ll set the compressor output to around 50 psi and fine tune with the one on the hose. Only needed one adapter from trap 1/4 npt to hose. Take the hose with you when you go shopping.
Used to do all my spraying at work, and set it up that way so I can do at home as well.
If your paint area is away from the compressor, you can just put a hose in between as an extension.
