I have a protective clear bra on my car. It does what it is suppose to do-protect the finish on the car.
What it doesn't do it stay looking good for very long. It is very soft due to the material it is made out of so the rocks will make nicks in it which looks amazingly like nicks in the paint. Of course, you can always replace it, but it is not cheap unless you do it yourself. I paid $900 to cover my Lexus, down from the $1700 the dealer wanted. After three years at least one piece needs to be changed. This is because some nimrod at a car wash decided to use his thumb nail to remove a bug and it now looks like someone used a rock to intentionally damage the car. I don't believe it can be fixed, only changed.
Now on a plastic vehicle like a SS it should be less of an issue. The color should be imbedded in the plastic material before forming. When a rock hits this it puts a divot in the material but it is the same color only duller. Not the best situation but I have lived with a Spyder for 70,000 miles and it is tolerable. But since there are two colors my guess is one of them is going to be painted. So the clear bra is going to help.
What is really going to happen, probably before this thing gets to market, is that someone is going to come out with a body wrap kit to cover the front end with all kinds of radical designs and paint schemes. It will cost as much as a good paint job but you can get some pretty radical stuff and you can apply it yourself although I hear that this is very difficult to do.
