Shinium - Brilliance by Design

I recently acquired a small bottle of EverBrite's ProtectaClear coating, a skin-safe, one part coating for metal jewellery. Supposed to be tough, hardwearing and so on, to keep metals safe from tarnish and oxidation and other damage. It's simple enough to use - a light, clear liquid which brushes on easily and dries fast - but does it work? Time to run some tests. I prepared a few bits of copper, as that tarnishes quickly and I have scraps kicking around my workshop. Also a chance to try out my new letter punches. Nice and clean, not 100% polished by hey - just a test, right? Fully degreased and prepped for coating. Coated and dry and ready to go. The zero band has no coating, the one a single coat, the two a double coat. Time to put these things through some punishment.   OK, top to bottom: A - On my keyring.
