Interesting post #7 :-)
I looked at the same issue with a Kona from a school. It requires a replacement "set" of EVA from the manufacturer and you need a vaccum bag to get it to stick on all the corners, but it can be done.
Talking to the guy who runs the school, he has the same problem. The EVA seems like a good idea but he showed me boards with EVA, including SB less than 6 months old and they look about 20 years old, while other more robust boards without EVA looked much better, and had a much better resale value.
I'm surprised SB don't push this to schools as a way to keep the board in service a lot longer.
