exponent,
Good luck with the experiment and I would be interested in your results.

Pete.

I think it's a good idea to try, especially with your Eclipse which is pretty good aerodynamically already, so laminar flow would effect it more than some cars where the flow is so turbulent that it barely touches the paint anyway.

(I think if I washed and waxed my Subie I would see a marked difference, not because of the airflow, just because it's usually covered in about 200lbs of dust, rust and mud. Someone once told me I'd need to file an environmental impact statement before washing my car. )

Lufthansa doing the same!

Deutsche Lufthansa AG, Europe's second-largest airline, is one of several that has begun washing planes more frequently, said Lott, pointing out that dirt on a fuselage increases wind resistance.

I have also noticed when I put RainX on my windows it makes them a lot slicker, so I don't just put it on the windshield I put it on all the windows. I don't know if it helps mileage or not but it sure helps in the rain. It might be something else you want to experiment with to find out. I have always seemed to get better mileage when my car was washed and had a good coat of wax on it. I have always thought if it was waxed the air would move over the surface of the car with more ease resulting in higher mileage. I always try to wax right before taking a long road trip.

Jet airplanes go a lot faster than cars, and their aerodynamic needs are far different. There's no question that a smoother, cleaner surface will flow air better, but I question whether it's enough to cause a gain worth the very small cost at the speeds that we go.

Rain-x and wax are great for preventing snow and grime from sticking to your car, though.

I use the RainX and wax more for the protective properties, but just thought it was worth mentioning. A little increase here a little there equals a lot over all. The largest cost to either is the elbow grease it takes to do it, not a lot of fun on 95-100 degree days, but those electric buffers sure help ease the pain.

yea we are having our airplanes cleaned and polished again also

I like american airlines ... smooth alum.. no paint no extra weight. easy to clean no touch ups needed always looks good.

on the other side you see cyclist in the wind tunnel and they add bumps to the back of thier suit to help the air break off them

oh well.

Because the car is a little shinier than usual, you will have a smile on your face, and will be less subject to being pissed off by other drivers, lowering the level of anger on the highway, and helping others get better mileage themselves. Because of all this, that trip will probably get you a bit better mileage than usual, but it won't be strictly because of the wax....
Im not driving when I don't really need to, but I take long relaxing drives twice daily--on the way to work and on the way home. I agree, when the car is clean and shiny it is easier to relax and enjoy the ride. The good mileage is a by-product of that attitude.
