I've done the spray chrome in the tent.
I say tent because we had one of those shed in a box with poles and a trap.
Very useful, but that's another topic.
I like the process. I had good first results with it and would spend the money, if I actually had money
and do all kinds of things.
It's a three step process with a base and then the metal type coating and then a clear coat.
You have to think volume when you go at it. The more volume of metatlizer stuff the better.
It holds up well on a glass bumper out front and most people can't even tell with mine.
There are a few online places that will supply the materials. Best to shop around.
Remember VOLUME spray of the metalizer.
You can see the corner of the bumper and it actually looks better in real time.
