So my new (secondhand) board arrived in the mail today and has a ding in its front which is a shame. The board is a Ocean Rodeo Mako 150, I'm looking for advise on how I should go about repairing the ding, or if it even really needs one.

I took it to my local surfboard store (thank-you to OKE Surfboards) and they said a cheap option would be to fill the ding with Araldite to waterproof it.

Please check out the picture and let me know what you think..
