Removing Fin

[Tom A]

Whenever I come to remove my fin at the end of a session I find its pretty difficult to get out, and involves me carefully putting pressure on it forward and back. I'm a bit worried that this leverage is putting too much pressure on the fin boxand may crack it, I have already noticed a bit of paint coming off. I've tried not tightening the bolts so much but there needs to be a certain amount of tension just to pull the fin in the whole way.

Can you advise anything I can do? Also is it ok that the paint has chipped or does it need repairing?
