I would use a mother's FX wax on them. It is a pure sinthetic wax with no abraisives or cleaners, so it won't scratch the surface. It repells water and dirt, thus making it a snap to clean at wash time
Yeah, I am going to do the coil over setup from MM in 3-6 months. I think I will be ordering a chin spoiler and grill delete soon. Then I will need the hood scoop, and lower it and I will be close..
