Just tried to spray some acrylic paints and every few passes I would have to stop and tear my airbrush apart and clean it. Now i am a bit slow and it took me four times doing this before I finally decided there may be something wrong with the paint. I had thinned it to three drops off the stir stick, skim milk viscosity. Used my jig-saw shaker and stirred it with a coffee stirrer for at least a minute. When I poured it out of the airbrush bottle, at the bottom it appeared as if it has curdled and was quite lumpy. AHA, the cause of my airbrush jams! Now my question is how do you all filter your paint to prevent such catastrophes? I bought some of those filters like you use for house paint, but I cannot get my paint mixture to properly drain through. Any and all suggestions will be appreciated.
