You do NOT drill the glass, you drill holes through the gap between
the panes (through the seal).

Aha! I'm glad you clarified that. I was reading that as drilling the
glass.


But what about jj's remarks in the OP, he was advocating drilling the
glass
wasn't he?

Don't know where the holes are drilled, advert just says 'a hole is drilled
in the top and bottom of the glass'. Could be the seal, but I get the
feeling from the ad that the glass is left in situ. Some good suggestions on
here, I might give them a go.

Back to my original Q - where can I buy the fluid and valve to DIY ?
