Rubber Coat your own magnets

[JTP424]

I've ordered a few magnets from K&J before for use in my tank (plastic coated ones)
They just sent this out in their emails:

I don't know if I would say it would be reef safe, but maybe for the magnets on the exterior of the tank!

Just figured I'd share!

i wonder if this would be good for frayed wires?
