When i was visiting the US, I saw a product called VentureShield, its a thin layer of film that protects the car against, rock chips, basically a paint protection film. I recently saw a place in Kepong doing the same thing with this film. Its quite a good thing as it does protect cars against rock chips, and has no yellowing on the film, its clear. I'm thinking of going in to do my car, as I just want the bumper and the hood protected. As I was told though it doesnt affect paintwork in anyway.
