Black cars and hot weather

Basically why radiators are black is that you WANT them to emit radiation at the highest rate.
You do NOT want your car to absorb radiation at the highest rate.

I thought most polar bears are more of a **** yellow than an arctic white.:p

I'm sure you all did the physics experiment at school regarding radiation from black bodies. However, the radiator in my P38A Rangie is not painted - it is natural aluminium.

I had this debate a while ago and was put back in my place very quickly by someone more knowledgeable.

Black radiates the heat away more quickly but does attract more in first place.
White cars attract less light/heat but emit the heat slower.

So its much of a muchness, black feels hot quicker but cools down quicker.

Choice.
