Just a different view, I have used a front end cover on all of my prized possesions. You just need to keep the area under the bra well waxed and clean of dirt and other accumulations and dry (remove after rain or driving in the rain). It does take a bit of care, but when you prevent the inevetible rock chips that will occur, it is a great investment.
I have always used the Colgan Custom brand, they fit good and tight and are great quality. I have one on my 1996 Black Impala SS and one on my 05 QSM goat.
They do take a bit of tending, but the protection is well worth it.
