Repainting a car for Aerodynamics?

[evolutionmovement]

They also didn't paint the fighter planes because the allies had air superiority at the time, so ground camo was unnecessary.

I'd love to have a bare alloy body with black paint over the areas that could reflect into your eyes. Would be hell for a lazy person like me to keep up, though.

I don't know about the relaxing color thing—pink's supposed to be relaxing, right? If I drove a pink car I'd drive faster so no one would see me in it. I think it's such an ugly color.

anyway, if you have an aluminum car like an audi A2 or a delorean you could save a few more grams by not painting them.

if you paint the car choose a relaxing color, this will cause you to drive slower and save gas!

the Delorian was Stainless Steel :P

Actually... I planned to paint it a "light" color as my car doesn't have AC and it gets upwards of 100-105 here in the summer LOL

hahaha... that would be AWESOME!

Blue, my friend.

I was planning on the "$50 Paint Job" (google it )

it comes in a "Sand" Color... a nice light beige color

There was an EPA joke about this, right around April Fool's day... the word was that the EPA was going to ban new cars from being painted black in California... they said that the extra heat created by the black paint caused car owners to run the A/C more frequently, which obviously burned more fuel.

It was a hoax. The study that the EPA actually did, showed that the temps inside the car are not affected by exterior color. If I can find the source, I'll link it.

BTW - the $50 paint job is not economical in any way, and doesn't work out to actually costing less than $100 for many people. Rustoleum isn't car paint, either. And don't use latex, please. LOL

Oh - if you want better interior temps, get some tint. There are many tints which reduce UV light, but don't ruin the transmittance of light through the window (you can still see, and the cop can still see in, to a legal extent.)

not if your car has NO insulation... I can burn the **** out of my hand by touching the inside of the roof of my car in the summer

and, yes, I know it can total upwards of $100 (or more)... but sure beats $600-$1000 for a shop job

Ok, wait until the hottest day you can, and get a friend with a lighter car. Put a thermometer in his car, and yours, in the same place, out of the sun.

Park them both in a parking lot in the sun, right next to each other.

Come back in like 4 hours. If there is more than a 2% difference in the temps, and you can repeat that effect over 3 or more tests, I'll call the EPA a bunch of morons.

*I've actually done this, back when I used to call them a bunch of morons.. now I call them scientifically correct morons.*

The fact that you can burn your hand by touching hot metal does not make it true that your interior is any hotter.

Oh, and removing the entire interior of my Civic made no difference in the temperature each day at 3 PM after being parked in the sun from dawn.

your telling me radiant heat doesn't make the interior hotter... well **** I think you just undid physics
