Serving Tray fix

I have a vintage serving tray that has been well used for many years and is showing its age.  I washed and scrubbed the inside but still the coffee cup stains lingered.  This morning I was clearing away the supplies I used to redo the pantry shelves when it occurred to me the solution was right there.  Using a scrap piece of silver contact paper I covered the inside of my tray.  The change gave my vintage tray a new stainless steel look that reflects the lamp light very nicely.  What do you think?
