Does anybody have experience on painting cast (not the extruded) acrylic prior to laser

Does anybody have experience on painting cast (not the extruded) acrylic prior to laser engraving? What type of acrylic in terms of light transparency is best for back-lit? I still cannot get satisfactory results.

What type of project are you working on?

@Alex_Krause Front panels for electronic, which I want to backlit.

Try to illuminate the edge of the acrylic if possible it will give a more even tone to the lighting… Also automotive acrylic spray paint will probibly be your best choice of paint to use

I cannot get even layers of acrylic paint. I paint with 4-5 layers until paint is fully light ‘resistant’ and only engraved text is shown, but on the other hand total paint layer thickness makes it harder to engrave evenly. I must say so far that painting is not my favorite thing to do.

I used the Rust-Oleum Universal Advanced Formula paint on a project for a customer worked fine. 20 or 3 light coats worked.
