Have you all heard of a company called Clear Guard
(
www.clear-guard.com). They have designed protection kits to protect vehicle paint from stone chips, bug acids etc. The kits are guaranteed for 4 years not to yellow, shrink or peel. The kits can be removed with out damaging the paint and the kits are clear/transparent.
My father-in law has had a clear guard kit on his PT cruiser for 5 months now and just loves it! No need for "black masks" which required cleaning and drying or bug deflectors.
