I have had good luck with this Testors Aztek paint in the past. This time though, when using a previously opened container, I get little chunks of stuff on the surface with every coat.🤬 So I picked up this little AK strainer at a local hobby shop. It wouldn’t fit my Paasche H airbrush cup because of the little lip in at the top of the cup, so I modified it slightly. I have a couple of spare cups on order just in case I screwed it up.😬 I’m amazed at how much dried paint crud it filtered out. The paint is going on very nicely now!🙂
