What do you use on your clevis pins (standing rigging and life lines)?
All standing rigging done this way and un-taped:
Turnbuckle upper ends are Sta-Lock fittings so no pins. Mast tangs done the same as in picture.
I only have pins on my lifelines at the stern pulpit where I have been using the cotter rings. I haven't decided yet whether to watch them more closely of do something else. If I ever have new aft sections made, I'm going to use lashings there as well.
My forward lifelines end in eyes and I use nylon lashings instead of turnbuckles. Compact and kind to hands and sails.
You may think the lashing suspect but I have seen a high tech, single handed, round the world racer with similar lashings used instead of turnbuckles for all of the shrouds. If it's good enough for that service, it should be good enough for lifelines.
