I've seen so many DIYers recommend Rub 'N Buff but I was always nervous to try. I finally did and I am so happy I dove in! It was way easier to use than I expected and dried so quickly.
I went with the European Gold finish. Only prep was cleaning the mirror (making sure there was no dust), and I used a cheap makeup brush to apply.
If you're wanting to try that Rub 'N Buff project, this is your sign to go for it!
The before was sort of a dark cooper color.
