what to use to paint plexiglass
If you're painting Plexiglas, not just any paint will do. Some paint may not adhere well, if at all. Acrylic paints work best on Plexiglas, and spray paints designed for plastic work as well. Clean the Plexiglas with water and a mild soap such as liquid dish soap, rinsing it off thoroughly afterwards. If your goal is for the paint to adhere well, scuff it up with a fine-grit sandpaper; paint doesn't adhere well to slick surfaces, so the sanding gives the paint something to grip.
