Ding repair on my s-core, please help!

hi, ive got a small ding on my s-core which does let water in unfortunatly but its a really tiny hole. I was wondering how i would go about repairing it?
Atm in my house ive got the epoxy repair powder and some superglue.. would i be able to use that? or do i need to buy a new repair kit with the epoxy liquid stuff.
Thanks alot in advance
