I started out painting with vinyl but now I only use it to paint eyes on. I've not found it at a craft store. I usually get mine off the clearance rack at Gander Mtn. for half of original price. I have to throw the xylene to it to thin it back down but it works after a little tlc. I don't know how many heads you can paint from a jar but I know it's quite a few. For me it got to be too much trouble base coating everything in white before the paint layer was put on.
