Sue. The wax works well for wake surfing. It does take a little while to get use to the feel. As long as you keep the deck of the board out of direct sunlight, or in a sock, you should not get wax on the cushions. There are a few good brands on the market. We have been riding with Sticky Bumps. They have a tropical wax for warm water and one for cold water. And a new one out now called 'punt' wax. Very tacky stuff.
