pearl additive

Hi, I just got a quart of bright white pearl mixing color from a friend and was wondering if it can be added to the paint I am going to use to paint my Dart. I am using OMNI pure white acrylic enamel, the pearl white is a synthetic enamel. I've never mixed colors or added pearls before, just mix and shoot. Will this work with my paint? I just don't want to ruin a new gallon of paint ! Thnaks for the help and all input.
