An auto coating instead of paint that is similar to the
baked-on Teflon finish and texture on a T-fal fry pan,
tuned up for application onto large automotive surfaces.
In addition to being a vehicle you could wash with a
high-pressure hose, no detergent, no wax, no chamois,
the texture may be
more aerodynamic than a perfectly
smooth surface, as has been found in submarine hulls.
||Any hard coating will have serious problems in an
accident: even with preplanned break zones you're going
to have some VERY hard and sharp extra bits flying
||^Teflon's not a hard coating, that I've noticed.
||It's a good'ish idea but is the substance in question up to the wear'n'tear ?
||I've wondered for a while why cars aren't Teflon coated. It's not that heavy (and car paint can be heavy anyway) and it seems durable from scratching. Maybe it wouldn't hold up to UV light, rain and wind well enough. You could also make the body panels out of Dyneema, which is just as slippery as Teflon, but that would be a bit expensive.
||Take a key to the bottom of your frying pan and you will
no longer wonder. Teflon's durable, but it's not _that_
