Thanks yall.
NEVER paint a steel door with a window black. First - no warranty.
Second - the window trim WILL warp - PARTICULARLY behind a glass storm
door. What direction does it point????

BAD idea, even if pointed north unless you have enough overhang that
direct sun will NEVER hit it.

From experience working for 2 different door / window companies.

As for what paint - other than colour? Automotive 2 part polyurethana
applied by an automotive body / paint shop is the best.
Good acrylic enamel is about second best. Sprayed if possible.

But again - and I can't stress it enough - NOT BLACK!!!!!!


Let me add to this a bit. My door is black and no problem but for a
couple of reasons. It does not get direct sun as it is under a roof
and there is no storm door. With indirect sun I've measured temperature
and on spots it was 35 degree over ambient.

That said, not just black but any dark color in the sun, especially with
a storm door can be a big problem. My son had a dark green door and
when the sun hit it you could not touch the door. You could get a
serious burn. Screen not so bad but a glass storm door and greenhouse
effect would bring a black door in the sun well over 150 degrees or more.

It will be worse than getting into a black car that was sitting in the
sun for hours. Think pastel.

I looked at a beautiful car for sale last Friday, but it had a black top
and black seats. Park it with the top down in the sun and it hurts a
lot to sit on it. You have to hover over it for a minute before it's
cool enough to sit on.** Especially if you're wearing short pants.


**IIRC I think that works, but I stopped buying cars like that 30 years
ago now I get tan tops and brown seats.

Also, when I had a dark green car and I'd come back to the block I was
parked on, my first thought was always Where is the car? since they've
been light colored, I see them right away.

And the accident rate is highest for black cars and higher the darker
the color.

And yet so many think black cars look like they're rich or something.
