To get this violet color, you will need to pick up a quart of paint and dump it all into the gallon of gray primer. Once the paint and primer are mixed, you will add the reducer and activator per the instructions on the can. Mike does it this way so if he needs to replicate the color again it will be easy to remember. Just make sure you use urethane paint and urethane primer.
To get the light blue that is on the truck in the lead image, Mike used HOK's SG-110 Marine Blue paint and a beige primer in the same manner as before: 1 quart of paint to 1 gallon of primer. The material for either the blue or violet will set you back about 300 bucks.
