I would think that the fact that the pedestal guard moves quite a lot would be a good reason for using butyl (as Mike said). But I am not an expert. And the fact that it worked for three years on my boat is not any kind of proof.
The only other experience with sealing a anything is with redoing the chainplates interface with the deck on my old C&C 24. At that time I used 3M 4200. If I remember correctly, it worked quite well for a while, but eventually, it is bound to become less flexible and starts to crack/lose the seal with the fibreglass (like all silicone). Eventually, I was told that butyl would have been better. Maybe we should ask the “Butyl Guru” – Maine Sail?

Marek My thinking is that there is likely some movement of the binnacle guard, and that LifeSeal will form a stronger bond than butyl. Can't say I have any evidence to back it up - sort of like 'my anchor is better than your anchor'.

Bruce, I had a similar problem with my pedestal guard and used butyl rubber. The pedestal guard with feet were moved up after loosening the set screws that hold it to the pedestal structure. This allowed butyl rubber to be placed around the threaded part of the feet. The pedestal guard was then pushed back down so the butyl rubber filled the penetrations in the deck. The pedestal guard feet are held against the deck. It worked. The cables run inside the pedestal guard and under the “bubble” located top/aft/centerline in the aft cabin headliner. Without removing the cables, I could not remove the pedestal guard. It looked like the bottom of the feet were threaded and designed to take a lock nut. If the above fix above did not work, I considered drilling holes in the “bubble” and adding lock nuts to hold the feet down..

Hello all, We have a 1994 C&C 37/40+, and we are replacing the stern and v berth mattress foam and fabric. I have noticed a very small leak which is coming from the starboard pedestal guard foot, where the bolts and wires penetrate the cockpit floor. We have stopped the vast majority of the leak by applying a small layer of aluminum duct tape at the point where the stainless tubing penetrates the stainless foot. There is a hard plastic spacer that fills the gap between the tube & the foot, but it doesn't seem to be made of the proper material to be properly water resistant. So, I expect this leaves us with water coming in under the foot itself, where it is bolted through the floor of the cockpit itself (which is finished with teak). What would you suggest as to the best way to seal this? The leak we get is coming down over the stern berth, and I sure don't want leaks staining our new fabric! I am thinking about loosening the feet & lifting up the pedestal guard, and applying butyl rubber to the bottom. If that works, great. But, how would I also more permanently stop water ingress due to water finding its way between the tube and the foot? Thanks for your ideas!
