[DeTomaso] Other Aero Issues

Let's stop this foolishness before somebody believes it.
Just because you can energize the boundary layer on a 1.25 inch golf ball
with dimples doesn't mean it'll work on a 14 foot car.  If you could just
reduce drag with flat paint, all those pretty commercial airplanes and
NASCARS would have flat paint on them.

All the ultra smooth paint finishes are also contributing to aero drag on
cars run at high speeds. A dimpled finish surface and positively effects
boundary layer performance, especially at the leading edges.  The matte
finish I applied to my Pantera this year was done just for that reason.
While it may appear to be just black primer, it was in fact a special mix
prepared to achieve a specific surface texture.  It was obviously
successful as I was able to maintain a 120mph average with top speeds
reached around 150mph...all from a 150hp engine.  Interior wind noise was
greatly reduced.  Will Kooiman was impressed with these results and has
indicated he may pursue a similar path at the 2009 BBORR.
A heavier textured coating applied with a roller seems likely.  My car is
black so his will be white with gold glitter much like the old acoustic
ceilings of the 60's.  That should get even more attention than the matte
black car. I can wait to see how it works at speed.
