I fixed the oilcan in my used Super Ego, Boiled up like 5 gal of water poured in the boat supporting both ends. Wedged a board under the cockpit rim and in the seat like a T and let it sit till the water was cool.
That fix lasted a couple of months!!! now its back.
I am not a good enough paddler to tell the difference. And everyone I talk to tells me its cosmetic, Knowing boat design from Sailing I would think at the speeds we go it doesnt matter other than during a flat spin in a longer boat. imo.
Don't do anything, just stand there.
