As the title says, Is there a good way to Thicken water based paints. I've been using Createx Airbrush Colors as my detail paints for about 6 to 8 months. I've never had a problem with the thickness of them until I used the Fluorescent Green. It's just seems so much thinner then the rest. I thought about letting it "sit" for a lil while (to thicken) before using it, but does anyone have any better idea or tips ? Thanks in advanced.
