Do a Google for "Road Wrap"

It is a clear sheet tlike the 3M stuff but made for temporary use. I have used it on SPFs to transport on open trailers and it works great.
We used it after Carlisle to "button down" the tonneau on the 289 FIA prototype to prevent the tonneau from chaffing the paint. I also just used it on my everyday ride to seal the moonroof when it went Fubar and was not closed fully on a rainy day.
Good stuff!
