Crease crack advice!!!!!

[LooseJuice]

Hi guys, I am in the process of restoring an old stick thats in really bad shape. I have fixed about 9 descent sized dings including rebuilding the nose and still counting!
I could really use some help/advice on what to do with these crease cracks that run across the centre of the bottom of the board (Pic below!). Obviously the nose has been stuffed into the sand at some point and flexed the board to cracking point but has not actually broke the foam at all! The cracks appear to be below the top layers of glass and are barley detectable by fingernail but obviously visible!

Do you think I should hack the glass out all the way across, refill and re-glass or just sand and glass over the top? Perhaps something completely different?
I do not want to take it to a shop and have them do it as I want to finish this beast off myself and give her a new spray job!
Your thoughts would be muchly appreciated!

I'd rather sand and glass over the top. As long as it's water sealed, it should be good to go.

Thanks Nightwing! Thats sounds much easier than cutting it all out etc. and much more appealing to me!
I am just a little worried about it all re-cracking when the board flexs whilst riding it, I guess this may be something I might have to wait and see if it happens????
Anybody patched up one like this before?
Thanks guys!
