Aside from a few small chips on the outside when the bit came through, all went well.

The worst part IMO is getting the hole started. I learned the best way is to brace the drill with one hand on the glass and drill, hold the bit at an angle so that just one tiny part touches the glass first, then slowely start angling the bit so that it's flat and 100% of it is touching the glass. This works great.

I also had a garden hose pouring constantly on the bit/hole for lubrication and it worked great. It also washes away the glass dust.

If it hasn't already been mentioned, try to drill from the wet side
This way any glass chipping won't be against your bulkhead seal
