I know this is not quite the same thing but a year ago I had my lithium White Ampera clear film wrapped at all the vulnerable points - front of bonnet, front bumber, lights, wing mirrors, boot lip etc. I did this as I do a lot of motorway mileage at reasonably high speeds and all my previous cars ended up peppered with stone chips. A year on and although the film has numerous nicks the paintwork is still sound. Before having this carried out I did a lot of research to find a competent expert and in particular one that used computer patterns to cut the film off the vehicle. The specialist I used is based in Bromley in Kent and I can thoroughly recommend him. If anyone would like his details please let me know.
