Sliced bread, anyone? We stole a trick from the rock racers and made our front skidplate from 1/2-inch cutting-board plastic. This is the same stuff that bread cutting boards are made of. It works amazingly well, sliding over every rock it comes in contact with. So far it has held up very well to TraiLex's 5,500-plus pounds of mass bearing down on it. It has definitely been used, as the Lex's ground clearance is still challenged by the trails we've driven it over.
