I think there are a few different ones out there and if done right they look pretty cool..

Yeah, used an old yoga mat because it is 1/2" flexable foam rubber that will bend if it hits something. Cut it at 3" then used double sided 3m tape to secure it to the stock airdam. I plan to also use it to make the rear airdam lower.

I saw some one used one for a mach-1 it is sweet looking, it's the white HHR with the blue wheels, don't remember His screen name.
