Hey Dolph
The bloke that sells Squid surfing equipment also has decking grip
for windsurfing boards. He only has one design, but comes
in two different thickness. I used it on my evo, works really good.
His PH: 9446 1993.
Make sure you clean the area your going to apply the grip
thoroughly, and leave the board in the sun for roughly 20mins (to
let it heat up) before applying the grip. Helps with adhesion.
Hope this helps.
