Does anyone have any pointers or experience with the best protective coating to apply to a watch and band to protect it from scratches and scuffs? People in the automotive detailing world swear by products such as Liquid Glass or Klasse or Collinite to protect their vintage and high-end showcars. These products are safe to use on metals and even list jewelry as an application. However, I never see mention of people using these products to protect and polish their watches after cleaning them with soap and water. Might this not be a good step BEFORE wearing a watch for the first time to protect it from future damage? For example, Liquid Glass produces a rock hard glasslike clear finish on surfaces after baked on with sunlight/heat and applied with multiple coats. It is buffed off of course as any auto wax/polish is, but it of course leaves behind a microscopic layer of protection. This type of protective coating is supposed to resist even rock dings on cars after enough coats have been applied. Does anyone out there have any experience with using such products on their fine metal watches? Did it have an impact on the long-term scratch/blemish resistance of the watch or did it only increase the reflectivity and shine of the polished metal?
