Jerry,
I use the the same magnets too, but to protect the white board,
I coated the surface of the magnets with liquid vinyl. Its available
at hardware stores and commonly use to coat tool handles. The magnets
are still very strong and no scratches. I used the red color to call
attention to users.
Good Luck,
