Mixing Cap I finally found the mixing caps. Go to art ( no space) primo dot com. They cost like 2 dollars and u get 10 of them. OH and I have a couple of reasons why u want these: 1. No one will say anything to you if your walking around with a Axe spray can (full of montana spray paint.) 2. Go to the store and steal paint out of spray cans and leave the empty cans on the shelve. 3. Good way to try different colors by mixing paints.
