how do you know if your board is water logged? Will it mess up the ability of the board if it gets water in it?
you will be able to see the water underneath the foam. and it can affect your tricks alot from the weight it puts on the board
if theres an area that you think is water logged then test it out. When styrofoam is waterlogged it becomes a lot mushier and you can press down pretty easily even with the fiber glass. You might have to let the board air out and then you gotta seal it up before you take it out again.
First. . . you have to suck out the "Poison." It will taste salty and smell like fiberglass, but it's the first step to letting things dry out.
I may not be right on this, but sometimes I think you'll get bubbles in the fiberglass of your board from the water getting in or the foam will feel like it's deteriorating (like it won't be there in certain spots). Hope that helps.
if its water logged, it will be a lot heavier and you do have to try and suck out the water and keeping it in the sunlight for a while
