Sorry if I'm posting this to the wrong forum. This just seemed like the place to talk about this. I was wondering if anyone had seen/tried this stuff called Sugru (site available here.). It's basically like modelling clay but it dries to be a flexible silicone plastic. Specifically, I was wondering if any one had tried it as it relates to fish tanks, as it seems like it could have some neat applications for DIY. It says it's safe with sea water on their site. I'm not sure whether it would possibly dry underwater, and whether it would be safe to do so in a tank with live animals in it. It says that it cures with the moisture in the air, so perhaps it would be. I was thinking of buying some in order to adjust something on my skimmer, but I was wondering if anyone else had tried it out. It seems like it has potential to be a useful new material.
