Mr T, I have been thinking about the same thing although my drive home will only be about 7 hours.
In the past for autocross cone protection, I have used 2 types of contact paper. The contact paper I found has a very low stick adhesive that doesnt seem to leave resisdue at all. What I have done is taken large amounts of it and spray painted it to somewhat match my car. Then cut pieces to fit. Also its tend to be *somewhat* compliant so it can somewhat shape to concave surfaces. Also I have found clear contact paper (its not really paper of course) found with contact paper in stores like walmart. This stuff is not real compliant and has even less sticky adhesive and not compliant so it doesnt stick well unless the surface is not concave at all.
You could bring a bottle Maguires spray wax/detailer, and use that on any surface you would apply the contact paper,to help insure you can get it of easily if you are worried about residue.
