lablover, take a piece of each of the Ultrakote colors to your local PPG paint dealer and have them match them to the "Shopline" brand. I've used the Shopline brand by PPG for the last 3 years and could not be happier! Besides that, they will match and mix in as little as 1/2 pint quantities at an affordable price. Keep in mind, it it a 3-part paint (paint, hardner and reducer) so you have to be very careful and be sure to wear the proper mask/clothing while painting. Also, they will advise you on the best hardner and reducer to use based on the temperature when you spray. Hope this helps___Everette
