I finally finished a GOG piece I've been working on. I learned that if you use Weldbond, it takes FOREVER to dry! I think next time I'll try silicone or something else that dries faster - I waited months for the glue to dry on this. I was pretty generous with my glue usage because I didn't want any problems with grout bleed. Anyway, it's finally done and I'm happy with it!
