While at the SEMA Show, I ran into a product called Road Wrap: A temporary clear film to protect your vehicle's finish when you need/want it.
You can use it on the front end of your car on the way to a car show—keeps bugs/grime off, and is cheaper than "blue painter's tape."
You could use it behind your fenders at the drag strip to prevent bits of rubber from attaching themselves to the vehicle's finish.
Or, if you're like me, you'll use it in on the leading edge of your hood and in front of your rear fenders where rock chips destroy the finish of your car when going skiing. (After six times up the gravel-coated roads of Mt. Hood, I'm down to the primer in some spots—the car is 10 months old!). Road Wrap will prevent this kind of stuff from happening.
The product adheres with a water-based adhesive that doesn't leave a residue. It goes on super easy and comes off just as simply, and it's disposable. Check out the video below for an example.
Road Wrap is available in two sizes: 18" x 100' and 6" x 100'; prices are $29.99 and $12.99, respectively—a lot cheaper than having to repaint the parts of your car that take the most abuse.
In addition to Road Wrap, the Louisiana-based company, World Class Concepts, LLC, offers Rug Wrap, which allows users to cover their floor mats in protective plastic, too.
No, I don't work for the company. However, this is a great product that deserves some attention.
