Thanks Chuck. Been using exposed raw cork for about 2 years now on my surfboards, paddle boards and bodyboards. Pretty amazing material. When exposed to water it releases a waxy, oily substance called suberin which provides all the grip you need without the need for wax. Cork doesn't actually absorb water, so there is no weight gain and the suberin never wears out. Also won't shred your stomach up like wax can, not to mention all the days your run out of wax, leave your board in your car and wax gets everywhere . . . .
