Re: Air Dam

[Robert Hogan <robhogan@freewwweb.com>]

Several years ago, while foraging for disposable drip pans (i.e. large
cardboard boxes), I found a 1/4" x 12" x 10 ft. strip of tranclucent
polypropylene flapper door material that had been discarded from a
furniture retailer.  The cut, formed and painted plastic strip made an
excellently deformable air dam as it held shape under aerodynamic
loading and obstacle contact but did not transmit significant loading to
the supporting structure.
