I use 303 all over my boat. Awesome stuff, so I got to thinking, what about on my board? It would keep it from fading, and maybe make it flow through the water better. It would only be slight difference I am sure, but why not. It makes my Gel Coat slippery enough.
I always wonder what the sun is doing to my board after the morning session and we spend the rest of the day kicking back with the boards in the racks soaking up the UV rays.
