I have used rub n buff for some small stuff and metallic finishes from a rattle can over the last few years, but it just doesn't come to the level of quality I want anymore. Maybe it's a sign I am getting better at this.

I am leaning towards buying some samples of the modern masters brand to play with.
For those that have used them, is there a particular color you go to for bronze, copper, pewter, etc...
Is there another brand you like over modern masters?
