How to fix a fin impact ???

Hello everyone this is my first post in the forum!
On a recent surf trip, all fault to my own got a little close to another surfer which has caused a very nasty gouge in the rail of my board !
The question is how would I go about fixing this ?
I've seen repair kits with qcell filler could i just use this to fill in the hole and glass over the top ?
Is this something I should really attempt or should i get it to a professional​ surf board repair shop? ( Problem being I'm based in Worcester miles away from surf shops )
Thank you in advance
