We've had our 4.8i since late February and we are slowly noticing little marks and such on the paint- mostly the hood. We already had to have the car buffed due to some strange white surface marks but now you can see the swirls. I guess we need to get a non-dealer full detail eventually. Anyway, what are the best options out there to protect the hood? I know there are clear bras but are those risky after having the car on the road for a few months? Any suggestions?
