I bought this to paint over clay, but I found it to be runny and thin compared to other acrylic paints that I had left over. I had to paint over the same area a bunch of times before getting a decent amount of coverage, and because of its thin consistency it was difficult for the crayola paints to cover up areas that had been painted with my other acrylic paints. I also noticed that the paint didn't have a very glossy or smooth finish when dry. In saying all that though, it was easy to mix the crayola paints together due to it being a thinner paint mixture.This product would probably be good if you were just looking to have a bit of fun painting, or if it was just being bought for young kids (which is probably their target audience anyway). :)
