After sanding I applied a thin coat of epoxy and "tipped" it with a foam brush. A light sanding and a couple of coats of varnish and it'll be as good as new! The refelction in the foreground is right where the glass is tapered down to the original sideboard.
The morning after applying the glass, I trimmed the overhannging glass and started sanding the (still soft) epoxy. The heat lamps help set the epoxy while I showered, so I could finish on my way out the door to work.
