under car aerodynamics

I have a sheet of 1/8" ultra high density polyethylene laying on the floor of my garage. Its gets slippery when wet so its something of a slip hazard. Are there any aero benefits to tacking the thing to the bottom of my POS DD to have a smooth under body? Cheers

I'd be concerned about the exhaust melting it or worse causing to catch on fire.

I was wondering the same thing a few days ago. but I would use sheet metal.

we are probably going to do this for our lemons car...(oops, I have said too much)

Yeah plastic probably not too goo being next to the exhaust.

autosportracetech did an article and testing on that on a car. Don't have a link but check the site out. Pretty cool stuff on there. :)
