The tape is often open at the top and bottom so air can flow freely.
I just replaced my lifelines and the attachment ends had been covered in rigging tape for many years (possibly 20 years?).Does rigging tape encourage crevice corrosion by potentially trapping moisture?
They're pretty much limited to turnbuckles unfortunately. I should pick up some decent stainless cotter pins. When done correctly, they almost never come outUsing this velcroed cotter pin avoids the problem:Johnson Velcro Wrap Cotter Pins
If you find them too pricey it is relatively simple to make your own with cotter pins and a roll of velcro tape.
