My board (the 6'0", the other one is at my aunt's) has two holes on the tail, not big (about 0.5cm) but both are getting water in, and you can even spot the foam on one of them.
There's a place that would ask me 10 bucks on each hole (fair enough to get the nasty job out of my hands


I bought silver tape and a thing called "Board Bog", which seems to be a temporary solution for dings. It's a mass, that doesn't get hard or anything, you just cover the hole with it. I left the board dry for two days and in the sun today (not sure if it was time enough since I've been surfing with it dinged for a while). I'm planning to cover the hole with this board bog, and cover it with some silver tape to get it even more protected, at least until there are no waves for a while.
Anyone ever heard of this board bog? Man, I hate ***king dings!!!
