I've cracked the tail on my surftech takayama scorpion l've tried repairing it a couple of times with the usual stuff and others, epoxy solaresin, two pack epoxy and as desperation tried alradiate and superglue.
Each attempt ends up as shown in the photo after a session, it does let water in. Before each repair l dry thoroughly. If you’re not familiar with the board it is quite thin on the tail, the rail saver on the leash is set correctly.
Any suggestion or tips would be great.
