I bought a tube of Rub 'n Buff after exploring a variety of options for turning brass hardware silver (e.g. spray paint, silver leaf, and leafing pens).
In the end, I decided to stick with the original brass hardware on the nightstand I was refinishing, which left me with a tube of untried crafting fun.
Which leads me to the frame I bought at Ross for $3.00. I didn't initially intend to put a silver accent on it, but I thought "Hey, why not." (note: click on photos to make them larger)
It's not a dramatic difference, but it satisfied my curiosity and demonstrated that the product actually works.
