Here is a candy coat car material I use on the majority of my car components and builds. Candy coat is comprised of a matte layer followed by several colored clear coats creating absorption allong the length of the car. This has become main stream in cycles car renders, however, because of the number of people asking about my node setup... I felt it best to post it here.
I am glad you like it. Its not a super complicated setup, but considering its recent following I thought I would share it.
Cheers, I am gonna use it quite soon as I am trying to modelise my car.
