1/4 inch high closed cell foam draft insulation tape.
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
Don't care if drag is increased - we're trying to increase MILEAGE.
Shark skin is "dimpled" or otherwise non-smooth. In rowing, the new carbon fiber shells have shark skin type coverings instead of smooth over fiberglass or wood. Why? They decrease drag through the water. Whether it's NET drag or immediate drag, I honestly don't know why we'd care.
Same principle applies here. By the way oranges are also aerodynamic with their "orange peel" skin. They don't normally move but if you've ever seen a cruddy paint job with "orange peel" (water in the paint usually), this type of paint job helps aerodynamics. Decrease cD for those who care.
So if dimpling, shark skin or orange peel effects help aerodynamics, you'll be helped with this type of covering. Anything that has a NET effect of getting the car through the air with less effort, even if it increases drag directly ON the skin but the surrounding air becomes net slipperier, then I say use it.
Looking to trade for an early 1988 Honda CRX HF (Pillar mounted seat belts)
Never noticed that before. Seems to suggest that they may need to work under more dynamic orientation to the direction of travel. I have read of owners finding themselves pointing the wrong way after braking and turning too quickly!
