In my opinion, the issue with many sealants is they "cure" or set. So a polyurethane or silicone sets and becomes less flexible. Further, many of those sealants do not adhere tenaciously to metal.
Butyl tape, on the other hand, remains sticky and pliable for a long, long time. That means it will flex with any movement in the hardware without breaking the seal. I still use LifeSeal for many applications where there is little potential for movement. But I'm switching to Butyl tape for bedding anything that may flex. Dennis C.
