hi guys, lurked here for a while, first time poster. woo hoo.

i have recently purchased a 2nd hand board, a WOW 14'er. I have paddled it 5 times, and now the bottom has gone dull, there is a defined line on the bottom, like a seam. any ideas if this is supposed to be like this? i can't find another one? but wasn't visible when i got it. hopefully you can see the shine to dull on the board.

someone suggested it was infact AST on the bottom? i have no idea, was sold as full carbon

any help would be great.

thanks
