Cwb Pure Wear On My Cwb Wakeboard.?

Wear on my cwb wakeboard.? - cwb pure

I have a CWB Pure Wakeboard 136cm. This model has a column in the middle, as most cusions landings in the water. I took it to a lake, a cable twice and got into a few boxes and table football. I note that the column is turning white and are fed and shaped fins. It is also somewhat difficult to maintain a balance in some way. Is it because of the spine? Should I a different table for this controller?
