Youtube has a number of videos on installation of a clear bra or paint protection film. For as many curved surfaces as a Cobra has it can be a little intimidating but take your time and it shouldn't be too much of a problem.
Be aware that the vinyl material doesn't like cold. Below about 65 degrees it can be pretty balky to work with.
Here's a link to a site that does pre cut kits for the Cobra:
