I got curious after Main Sail's earlier piece on butyl tape, so I got some from the online RV place and used it when rebedding locker hinges. Impressively sticky stuff.
Considering that it seems to stay sticky for a very long time--I think MS showed something that had remained pliable and sticky for over a decade?--and seems easier to work with than a caulk gun full of Sikaflex, I'd like know what its limitations are, if any. Is butyl tape suitable for all above-waterline hardware rebedding jobs? Say for stanchions, clutches, etc?
I've used it on every type of mechanically fastened devices that you can think of and it works great.
Limitations include feathering a joint and smoothing over the bead. I can't think of any use on deck where I would not use it. As i said 80% of my boat has yet to need re-bedding. My genny tracks for example were done at the factory with butyl nearly 30 years ago and they are still bone dry with not even one drip..
