Its a full sythetic paint, and hardner is optional on it. The hardner was reccomened for use on metals because it creaters a harder paint coat with less flex, but since it was on my fairings I went without it hoping it would be better. Its all dried now, it took about 2 hours to fully dry. I choose purple becuase its my 3rd favorite color, and no one has purple bikes so it stands out pretty well even on the road. The silver primer I used gave it almost a two tone looking paint which I'm liking at the moment. Do you all have any ideas as two how long I should wait before sanding down the two peices that have minor flaws? Also how long should I wait before I compound them and wax them?
