My boat (Foxcub 18) has some leaks in the topsides, where the shrouds come
down to the deck. The shrouds attach to U-bolts which pass through the edge
of the deck to a blind fixing inside. After messing about with a hose, it
appears that water is getting through between the U-bolts and GRP.

Since the fixings don't seem to be removable, I'm thinking of sealing them
from above, using some sort of mastic or highly-flexible sealant, perhaps
squeezed in with a syringe. What would be a good material to use? Any other
way of fixing the problem?
