I had a Zone VI 8x10 and it is a very sturdy camera. I use a 120mm lens and it was not easy to use on that camera so I sold it and bought a ebony 8x10. But what I wanted to say was the fitting I believe are gold plated and if you use anything on them you will rub off the finish. Mine started to pit alitlle so I used a polish on them but that was all. Have fun with the camera. Fred Picker made the cameras for the photographer big knobs. I like big knobs, solid wood, I like wood.
