Ok so I have a pretty old board (Patterson thruster) that I want to take out but the only problem is, is that it has minor delamination. There isn't a crack or any thing that makes the board not water tight, I simply think that this 5 inch delamination on the left side near the rail was caused by being used for many years. It doesn't stay in when i push it down and it only goes down maybe 3cm tops. The shape of the board is still the same in that area but i can tell that its a minor case. Am i able to surf this or should i just stay off of it until it's completely fixed?
