Any glass shop will cut the pieces needed and they won't cost much at all.

Also, only flood issue would possibly be on a power outage IF the silicone let go. But let me tell you, where I live, I get 10-12 outages a year, some for hrs at a time. Never one did my tank have an issue. If you have a standpipe style drain in the overflow you won't drain the whole tank anyways..

ahah I love how you're half arguing with urself

I don't see how I was arguing or contradicting myself. I said it doesnt stick to ABS Very Well Then I said I have used it with No issues.

Meaning, even though it does not stick as well to ABS as glass, I had NO ISSUES!! Meaning, in my overflow setup, it never exceeded the bond strength!

Where is the arguing with myself???

ahah I just found it kinda of amusing the way it came across to me b/c in my mind if something doesn't work very well then typically you should expect issues by the very definitions of the words.

I know you can make things work in less than ideal circumstances (sanding etc.) but I'd just prefer the ideal circumstances.

Not trying to start something just amusing how it was set up sounding like you were not really for it "not very well" but then it all of a sudden sounded like you became all for it "no issues" Like your first post was from one person and the next was from another... just how it sounded to me

But I do get what you're saying. It's not the best bond in the world but in your experience it seems to work very well for the application as you have had no issues.

Personally, I still wouldn't do it.
