I made a lot of glass tile pendants with Diamond Glaze before I found out it was not waterproof. I am now going to switch to making them with resin.
But in the meantime, would buffing the glazed pendants I have with something like this help improve their wear in humidity? They already have many layers of Glaze and I don't want to put resin over them because they are built up enough right now.
