Vortech magnet rust

[mermaid_life]

Today while cleaning my vortech pump, I found a small nick that was rusted on a mp 40 magnet. I cleaned it with vinegar just to get the rust off and rinsed it. Magnet hasn't swollen or anything. Thoughts on whether I can coat the nick and get a little more life out of it? I tried epoxy, but i think the un-eveness will make it run off-kilter and loudly.

I wouldn't risk it
