How do i fix those scretches/cracks on my monofin?

[Alexander Nordqvist]

I was about to go out and train with my monofin, but i noticed today this scretch on my monofin. I have reached out for help from the guy who has made this fin but he was unclear and i asked him for more information, but haven't answered jet. There for i ask you guys if someone know how to fix this scretch?

I don't know what material it's made out of perhaps carbon fiber which may require some sort of a repair.
But my monofin and my regular fins are so completely scratched and gouged and covered with imperfections from the coral they frequently hit that it would be hopeless to try to repair any of them.
And I've never thought about doing so.
They go for years and years with all those scratches and gouges and they still work.
