Waterweld-epoxy
 

So I found this JB weld brand epoxy at canadian tire today. Anyone know anything about it and if it is reef safe. It says it works underwater and is safe for use on potable water lines. Should I give it a try in the reef or is it too risky? problem on this type of thing is there is no ingredients listed to compare it to commercial reef epoxy.

It might work fine but then again you are what? saving 5 dollars on epoxy when you have spent?? $ on your tank and inhabitants.

If its good for potable water it should be good for your tank ... anything that is good for potable water cant have any poisons, lead ect ... in it ... the only thing I would look for is that it doesnt contain any copper or bronze .
