Reflective Paint for Light Fixtures

Q. We make light fixtures. What is the most light reflective paint that we can apply to the inside of our domes? The dome is made from ABS plastic.

A. To the best of my knowledge white paints are the most reflective, which is why most of the painted reflective surfaces that we see on light fixtures are white. Since you are using ABS plastic you have little alternative but to use an air-drying coating system, and the one that is very popular for such applications is polyurethane.
