Is the pearl something you added to a white basecoat, or is it a premixed pearl white? If you added pearl flakes?? to a white, how much do you add? Also, how much candy red and blue did you use? I know candies are a variable as far as how many coats to achieve the effect you are looking for, but how much did you use? I am looking to do, oddly enough, a pearl white, candy red, and candy blue Forbes Cobra pylon racing biplane.
It is a Dan Santich design, with a gull wing top and inverted gull lower wing.

Thanks
Jeff
