Hey guys I have an opportunity to buy a coosa HD for 20% off at a local dealer, but here's the catch this particular kayak is their last one in stock which became their demo model. It was said to have been only put in the water just once which I believe based on how good it looked, however when I flipped it over to inspect the hull I noticed a couple of indented warps horizontally from where they had it stored across 2 flat 2×4's. So I asked the guy about it and he said yeah those will come out and said we've had good luck in the past with em coming out. I ended up taking it out and testing it on the water it felt fine and looks like it's in excellent shape minus the warps but those still concern me. So my question is should I be concerned or is that a fixable problem?
