Is Flex tape reef safe?

[mochaclownlover]

I saw the infomercial for this and thought that this stuff might be a good tool to have on stand-by in case of aquarium leak as a temporary fix, but I'm not sure if it would be reef safe. What do you guys think? I'm posting the link to the site bellow.

I think its fine. Not a long term solution.
