First a quick clean with Colorantic Cleaner and Varnish Remover. Using this cleaner is very easy as you spray it on. Just a spray of the cleaner on the frame and let it sit a bit then a wipe clean with a soft cloth until nothing is coming off the frame onto the cloth. I also taped up the mirror using painters tape so I wouldn't get any cleaner or paint on the mirror making the clean up very fast.
I let the paint dry 30 minutes and took out Colorantic's Grey Storm Wax to age it and protect it at the same time. Using a wax brush I brushed it in the crevices on the frame and here and there on the outer rim and on the rest of the frame. I let it sit for about 10 min and then wiped back the wax I didn't want and left darker areas where I wanted it. Wax is great to work with because you can always take back what you don't want or add more easily.
That's it! It was so quick any easy and I now like the look as you notice the stain glass around the mirror more and it looks aged but lighter and fresher!
