BS. This is an easy fix. Just make sure you clean out all the old silicone from the glass. Then just silicone in the new piece, and make sure that you use plenty of silicone (a messy job that works is better than a clean job that doesn't, IMO). Tape off on the glass for clean lines.
I completely re-siliconed a 125g tank with overflows because of a leak between panels. I didn't have to replace a glass panel, but its about the same procedure. It's been running fine for about 10 months now.
