I took another look at this because I like the combination. How did you polish out the corian ???
A friend of mine owns a cabinet shop. He gave me the Corian and the polishing pads to finish it. Micro Mesh wet would probably work just as well. It is not polished to a perfect shine.... Just enough to get rid of the scratches.
Another product I have started using is Zona polishing paper. It works great on pens. It comes in 6 grits. A 6 sheet sample pack is available on Amazon for less than $12. Sheets are 8 1/2" x 11". I cut it into 1" strips. Works great!
The gold tubes are knitting needles I purchased at Wally World and cut to size.
