Cheers guys,
I Think I will use Stribos method as there is no crater like hole, it is more of 2cm crack I guess, so no real valley to squeeze the Aqua Knead it into, as for cosmetics the board is probably 6 to 8 years old and I feel that the epoxy araldite will fix the problem.
Thanks for all your options and reasons why, I feel much better about what I am going to do now.

Stribo look out if it goes pear-shaped mate

I will have to catch you in my Jeep coz I cant sail as fast as you

Cheers guys and good wind in ya undies and the water
