3m 5200?

[apayne]

Hi I was just wondering if any one knows if 3M's 5200 Polyurethane sealant is safe to use in reef tanks? I have read that people have used it in large systems, but I just want to make sure before I use it in mine.

Thanks,
Aaron

I am using it on my system. No problems.

Thanks KenT,

I sort of thought it would be fine, but just wanted a "second opinion".

Thanks,
