True, mass savings would be very minimal (glass vs. carbon).....~1-2lb a
vehicle....that's why I questioned the benefits of carbon bumper skins when
compared to the costs.

Uhhh...so you're saying there's no advantage to a carbon part over a glass
part (holding resin constant) in terms of structural integrity??  I'd say
you're ignoring both the 20% increase in tensile strength of carbon and the
principle of combined action.

Or maybe I've missed the boat entirely.  Toot-toot.  -John
