Your local autoparts store should have it. I'd go with the 1" wide since it's easier to work with. Typically it comes in rolls, most cases 50' long. Like mentioned wrap tends to cause corrosion beneath it since it holds moisture some say. When I used to run wrap on my ATVs what I would do was after a wash I'd start it and let it run for a while to evaporate all the moisture out. I took the wrap off after 2 years of running in really harsh conditions and didnt have any problems. Or if you're concerned paint them with high temp paint and then wrap them.
