Nissan develops paint that keeps cars cool in summer heat (www.asahi.com)

Nissan Motor Co. said it has developed a new type of paint that significantly reduces the temperature inside vehicles parked in direct sunlight.

The surface of a car coated with the innovative material remains up to 12 degrees cooler than that of a vehicle with standard paint, tests showed.

The company said the coating material can help rein in the temperature rise not only on the car's body but also in the vehicle when exposed to direct sunlight.

Mythbusters did an experiment with a black car and a white car hitting in the sun. The black car was 12 degrees Celsius hotter. Claiming that the paint makes no difference is such a weird take. I thought this was common knowledge as well as many people I've met avoid darker colours in summer and such.

Summer was hard on me in my teenage goth years.

Can't really get many light shades of black.

Careful, I don't think that mask is n95 or anything.

Speaking of huge and inconvenient, if you're a cheapskate, just get a car cover. Always helped my motorcycle.

I bet the interior of your motorcycle was WAY cooler after that.

It was! Also, the exterior wasn't too bad, either

What's the cost (financial and environmental) of repainting a car vs using a windshield visor that's at least twice as effective at reducing heat? Painting a car with this stuff would cost thousands of dollars compare to $20 for a visor.

I'm not talking about repainting anything, why are you moving the goalposts? Just buy a white car AND use a visor, what's wrong with that? And in the future, if this stuff is actually good, maybe all cars can come already painted with it?

Just buy a white car AND use a visor, what’s wrong with that?

Nothing's wrong with that-- why would I assume you're talking about regular paint when this whole article is specifically about a single type of new paint developed to keep cars cool in heat?
