The hardware is great, so kept them 'as is'. I cleaned them but no deep scrubbing or chemicals. I have ruined a few pieces in the past with too much cleaning, stripping off the beautiful patina. Learned my lesson!
I had Vos Glass cut me a 1/4" piece of glass to size with a nice pencil edge. If you are in the GR area, I highly recommend them. Nice people, super fast and great pricing.
I simply sprayed the back with super white high gloss Rustoleum and just because I like to go the extra step, did a clear coat for protection.
It takes many coats to cover well. I wanted to make sure all grease and fingerprints were removed for a great finish so cleaned glass with denatured alcohol.
