Hey everyone, I like to airbrush my projects over spray painting and hand painting but I was having trouble with inconsistent paint spray from my brand new airbrush. I made sure the brush was clean and that the paint was thinned and was still having trouble. In a flash of frustration and almost anger I thought about something I read a long time ago about people in the automotive paint business straining there paint before putting it in there gun.
So I tried it out and strained the paint that I had already mixed and thinned down and it actually seemed to work 100% better. What are your thoughts on this? |

What I do when I shoot is utilize disposable plastic cups to mix the paint and thinner in. I use a toothpick or bamboo skewer to mix the paint, then pour it directly into the cup of the gun.
If you are using a brush to transfer paint, that might be the problem, just carefully pour it from the jar after you have mixed it well by shaking and stirring with a toothpick. Also it helps to have a scrap of plastic, I use a model car frame('70 Chevelle)to test the paint on before I paint my real subject. If it doesn't lay down right I can tend to it. What paints/thinners are you using? |

I don't usually strain the paint when I use my airbrush, but I do strain the paint mix when I use my HVLP gun for larger projects. We used auto paint last semester for a project for my ID class, and we were instructed to NEVER put paint into the sprayer without straining it first. I'm not sure that hobby paint needs the same care before loading the airbrush, but if it works better for you I don't see the harm in doing it.
Not sure if you've done much airbrushing before, but something you might want to do after each session is to dis-assemble the entire airbrush and soak the metal parts in acetone or similar solvent for a few hours after painting. I find that sometimes, even after I've cleaned the gun and can find no trace of paint, there is often a slight residue left behind on some of the metal parts. So now I soak everything after use. Don't soak any plastic parts that might be on the gun as the acetone will eat them away.

I strain the paint every time. It's a pain in the ass if it gets clogged up.
Well, at least I used to. I hardly ever use my airbrush ever since I gave up on my art. |

I just started training my paint the other night and have found that taking some panty hose and taking the cap off the paint bottle and putting it over the threads and screwing the lid on and cutting the excess panty hose works great. Thats too bad that you gave up on your art, I hope that you get back into it some day. |

If the paint is spattering intermittently while you shoot, it could be the gun is dirty on the inside like starwarsgeek said. I had this happen with my gun last summer, took me a while to troubleshoot it, gun was sputtering really bad. |

I won't be going back to it unless I go to school & learn computer graphics. But my fighting with paint days are long gone. Except for my toy customs, I'm trying to get the last of them done because I DESPISE PAINT! I never wanna work with paint again. |

I have a bit of a love hate relationship with paint myself, I hate the upkeep and the cleaning and such but I love taking a custom to the next level with paint.
