It would be cool to see how this looks after it's been on the road for a while. See if there's any interesting shapes from the engine/exhaust/airflow that show up.

In the winter on a sunny day it will suck trying to find your car..left it one color, found it another color

I had toy cars exactly like this when I was little.

"Kids! The car is brown today; grab your coats!"

Yet there is a perfectly good hose on the ground right next to it they could have used.

I found the commercial! I had these motheruckers back in the eighties

All I saw was someone pouring black paint on someone's car, never saw it "change" back...

As a person that has driven cross country in the US, I have experienced insane hot rains that nearly (and sometimes completely) blot out visibility. Does this not seem like a bad idea to make your car become "invisible" (dark color change might not register with human vision if the color change occurs at the moment that visibility is impaired) with different temperatures of water? I imagine seeing this red car disappear and then THUD CRASH BANG: rear end collision.
