This might ultimately be a question for Maine Sail, but I'm sure others know as well. I've read a good bit about butyl tape on Sailnet, and have discovered that at least some of my boat's hardware was bedded with it, and definitely the hull-to-deck joint.
I've also read here that some things are called "butyl tape" but aren't really.
So I went to my local RV shop and found this stuff, which is off-white/beige, and I'm very happy about that. Should blend nicely. It's labeled as "Butyl Tape", and feels like the putty that shows up oozing from stuff on my boat.
Is this the right stuff?
By the way, if it IS the right stuff, should I use butyl tape to rebed my in-board, deck-mounted, genoa sheet tracks? They are through-bolted and need to be rebedded.
