If you want monocolor like I do. Here is a cheap option that my daughters boyfriend turned me onto. I want to get rid of the red PLASTIC on my car which makes a wrap or vinyls my only option, so I thought.
He cut plastic coat down 50/50 with thinner and sprayed his car. Once black the he did blue. It actually turned out pretty damn sweet and cheap!!!!!! And peels right off when you are tired of it or want to change colors. I will be trying this in the spring. Smart kid.
