While I can't give any insight on a vehicle wrap, I can make an informed comment about the wrap I have on my drift boat in the picture to the left. I had Coho Designs out of Portland, Oregon do a graphic that looked similar to the Oregon Ducks football helmet from a few years back and then wrapped a 12 mil overwrap that is the same thing as the motocross guys use on their pit/mechanic trailers. I can say that it takes a helluva drag on that overwrap to get down to the base graphic. On the river you are exposed to all sorts of limbs, downed tree with root balls, big rocks etc and I have only torn trough one time and that was at a boat launch where I backed into a railing and drug it up the side of the boat for about 2". So, in short, the clear wraps do work well. They will show small indentions in the wrap vinyl but should protect the base paint pretty well. As for cost, my entire wrap was $1100 but most of that was the design of the graphic underwrap so, say $550 ish for the protective wrap would be an approximate cost. The thickness is the key though, so don't scrimp on that if you go this direction.
