Holding up to the heat.
I used this on some of the metal trim of a natural gas light that sits in the Texas sun. The top of the light gets very hot from the burning gas as well. It has been up for almost four months now. There are no signs of bubbling nor peeling at all; the finish looks as flawless as new.
In my case, I do think that the look of copper is a little off in regards to realism. But I think it is the fact that I painted over a textured surface, though. If I had painted over a smoother surface it might very well have looked more like authentic copper.
The paint was perfect. Loved the color, it was dead on. Excellent service. I was amazed at how fast it got here.
Covers well, takes several coats as expected to make the metal look perfect.
Worked well. Nice copper color. Paint seemed to go a long way.
