Its hard to describe, but if you but I fixed mine by cutting a piece of card board to shape, then inserting it inside to helm and taping it to the top and sides to pull the Brim forward a little bit, as it comes forward it flattens the bottom and looks fine. When I resin it tonight, I should be able to pull the card board insert after it cures so I can fiberglass the inside without it getting in the way.
