By the way, don't know if it makes a difference, but I wax mine regularly with Turtle Wax Platinum Series. The shine is good, but the hard shell protection is what I like about the wax. I also have the factory bra from Mazda. I put it on anytime I'm going to be doing instertate driving. I wax the heck out of it before I put the bra on and I never leave the bra on for more than three days to take it off, clean it and rewax the car. I think that's a big part of why this car doesn't have any dings. That .... and a whole lot of luck.
