What's the best paint to use on a leather jacket?

When a project calls for paint rather than dye I always use Tandy Leather's Cova-Color, I have not found any better product. It stays stuck and flexible so no cracking or pealing off. It comes in a lot of colors and they can be mixed with no trouble to get what ever shade you want. The Cova is water based so if you goof you can wipe almost all of it off he leather with a damp cloth then start over on that spot. Once dry it is permanent as one of my shirts with the neon orange spot in front will show. One other thing, I find the best brush for the Cova is one with a "Taklon" bristle. American Painter is one brand of brush that is easy to find with the taklon bristle.
