After much work, I am almost finished painting my posterboard with the paints from AFFO$'s paint list, but I noticed that it seems to be much too shiny. I bought some matte finish but when I tested it on a painted piece of scrap, it seems to make it more shiny than it already is. Is there a specific brand or type of paint that anyone knows that I could look for? Heres a picture so you can see how see its excessive shiny-ness.
