We ended up filling a 1quart ziplock baggie full of super hot water. It was
so hot I had to wear mittens, which is fine because ...IT'S WINTER!!


Don't do this on your plane.....

I thought it would be cool to wash my car in the winter with warm / hot
water in a bucket, and while I had nice and comfortable hands when washing,
come time when the car cooled down to freezing, the paint crazed from the
expansion from warm water, and contracted from the cold weather which
caused the crazing.

As a (former) painter, I offer that the reason the paint crazed may have
had something to do with the paint film depth. If paints are applied in
the recommended thickness, they are much less likely to craze from rapid
temperature change. Add another paint job and/or multiple coats of clear
and crazing becomes much more likely. Also, improper substrate
preparation will allow crazing over time and accelerate with rapid
temperature change.

When we used to do custom paint jobs in the 70s, we would cool the
finish down gradually on a completed vehicle. We would go from shop temp
of 68 degrees to an unheated stall at 45 or so for about 10- 20 minutes.
After that, it was out to the open. Never had one craze.

I did have a guitar paint job I did craze after a night out in the car
at zero. Again, 40 coats of clear lacquer will do that.
