We used 3M "Clearmask" on my buddy's 66 Suburban front end. Really good stuff but hard to work with. As with all 3M products it's also very expensive.
My dad, back in the day made a shield from sheet metal when he went to Ak on the Alcan hwy. That also worked great when grape to golf ball size rocks were trying to hit the trailer.
