reef-safe epoxy? LR gluing?

[sharuq1]

I am looking for some reef-safe epoxy to coat a magnet in for a project I am doing but I need help to find it. I found some "Lepage marine epoxy" but they say it is "not food-safe and not recommended for aquarium use".

Anyone have any other ideas I would really appreciate it!

Also, unrelated to above question: What is the best product to glue live rock together? I have tried the putty-reef sticks they sell in the local fish type stores and nothing seems to stick very well, just resulting in a mass of the putty between the rocks that does not stick to anything. This does not result in stable rockwork like I had hoped....
