I would like to paint acrylic sheet (Plexiglass) with acrylic paint. Both the sheet and the paint are opaque (black or white); single color all over.
What kinds of paint should I use? What kinds of paint should I avoid? Are all acrylic paints created equal? My local home improvement store carries acrylic paint, and they can make a variety of colors on the spot; would that paint work?
How to prepare surface? Do I need to apply primer first? If so, what kind of primer?
What can I use as varnish on top of the paint?
To put this question into perspective, painting is only the 1st stage of the process. In the 2nd stage, I will burn off the paint with a laser. So, if I've got black acrylic with white paint, and I ablate the paint selectively, then I will have black details on white background. (This is not unlike LaserMax sheets.)
I know how to do the laser. I don't know how to do the paint.
