I've been visiting the local car lot on Sundays and checking out the different colors. I currently like the Winning Blue, Titanium Gray, and Velocity Red. If I keep it as long as my current car I'll have it 10+ years and was curious if there is any difference between metallic paint and mica paint in the long run. Does one fade faster than another. I wax 1-2 times a year, for those 3 colors in general are any known to fade faster than the others over time. Thanks.
