organic hard surf wax? I made some organic surf wax with 4 parts beeswax and 1 part coconut oil. The wax turned out to be sticky but had no tack. 

I'd like to make wax for warm water that forms a layer of hard bumps on the board when wax is applied. 

Not sure how I can achieve this w all organic items. 

Any suggestions?
Carnauba wax is a high-melting wax that should be suitable. In the Wikipedia article cited,
"Carnauba wax can produce a glossy finish... It was commonly used in its purest form as a coating on speedboat hulls in the early 1960s to enhance speed and aid in handling in salt water environments. It is also the main ingredient in surfboard wax, combined with coconut oil."
