boot leak

[Mont5.0]

Anyone else got the problem of water getting trapped in behind the boot lid carpet? I experienced this for the first time today, and was quite shocked at the amount of water that came gushing in through the boot latch(seems to sit in between the two layers of sheet metal which make up your boot lid). anyone know of a easy fix for this problem? was thinking of drilling 2 small holes either side of the latch so it naturally runs out whilst the boot is closed. I would prefer not having to drill holes if able to do other ways??
