You could just buy some liquid latex from a hobby store and put a few coats on any magnet that works for you.

The problem is finding magnets that are big enough. I have thick glass so any mags strong enough are $$$$$$$. I might as well buy sure-grips and modify them. If anyone finds anything please let me know

Hard Drive Magnets
 

At work when we decommission servers we physically disassemble the hard drives for security. This leaves us with a nice collection of rare earth magnets that will break finger bones if your not careful. The Magnets are larger than the buttons above and would require they be cut to size but I'm willing to offer a couple to someone in the lower mainland if they are sincere in trying to make something with them.
