So I picked up a 60second set, 2 part epoxy... when they said 60 seconds they weren't playing. I actually had to get the epoxy all the way thru the 3" tip of the epoxy applicator in 60 seconds before the entire tube set. stupid thing. why make it mix acrosss that much tube if i have to keep it flowing constantly... not good for a small precise job like this... maybe if I intended to smear it across a huge surface I would be happier with this crap...
but I digress...
It's holding superbly. I have no doubt that this joint will withstand the test of time.
and so while i'm at it.. here is the old tank where it sits.

and the new one in it's place.

I'm realizing it will look better with some art on the walls. redecorating sucks.
