I actually just talked with a guy who does this. He said to use a product called camoclad. He has done several atv's and utv's and said the product is great and holds up against abuse. He offered to do mine for $100 plus the cost of a couple rolls of the wrap. I will probably hold off for a year or more and let my plastic take some abuse before I cover it up.
