A couple years back I started to have trouble with my go to paint, wicked colors by createx, going through my micron. Even thinned down with w500, 4011 or 4012 I was starting to get the WORST tip dry and regular clogs. Something in the formulation changed I think. Older bottles still sprayed fine, but all newer ones I bought, regardless of store were becoming an exercise in frustration. I tried a few flow improvers, balancing clear, and more... nothing really worked. Home made flow improver made from glycerin helped a bit, but made the paint dry too slow. Recently a friend that does miniatures suggested Liquitex flow improver. I was skeptical to be honest as I never cared much for their paints, and thought that it was probably just repackaged glycerin. Well... there was a bottle on sale at a local craft store, so I figured what harm could it do to try at least. I have to say, I am shocked. It worked wonders. You reduce it something like 20 parts water to one part reducer, and just a drop of it in my cup along with reducer and paint, and the change was amazing. I am finding that tip dry is all but completely gone, the paint still dries fast, the crosslinking is delayed so I can erase for up to 15 minutes or more even with the paint dry to the touch, and it still cures hard. Wicked now sprays like it did when I first started using it, and I am going 20 to 30 minutes at a time without even having to pinch the needle to remove any dried paint. It's working way, way better than my home-made flow improver. Best of all, no clogs at all. Wicked tends to dry rapidly on the walls of your cup, and I think sometimes that dried paint was making it into the air channel, causing my clogs. The flow improver pretty much has entirely stopped that. One small downside tho, was when the paint did dry on the sides of the cup after an hour or so, it was a bit of a PITA to clean. It had a death lock on sides and I had to use my ulrasonic to loosen it before I could clean it out. So for anyone struggling with Wicked like I was, maybe pick up a bottle. They are pretty cheap, and considering that you reduce it 20 to 1 and only use a drop at a time, even the small bottle will last me forever. I'd be interested in anyone else's recommendations on flow improvers to help with detail brushes like the micron or infinity. and tricky paint. If something like this made such a change for me, I am sure that others have great products or home made recopies that are even better.
