The other day I came out of a good session to find that 3 of my futures box's have been damaged, while 2 of the are fairly simple repair one of them has collapsed about 20mm into the foam.
Ive been learning basic repairs on my boards for a little while now and I'm hoping that someone on here can give me some info on how I should go about it. The box itself is still intact and has had no crack to it at all. Last time this happened I took it to a shop (different fin box) and the bloke just built up a wall with resin.
