The tar is deeply embedded and I've never had any issue with stickiness on the hands or running through pulleys. My end hangers here  by the way are old sash weights I salvaged many many years back. Come in weights of 2 up to 8 lbs. Bless the bowline!

Can anyone decode the #N gauges listed?  IOW, is there a table or formula that converts the numbered sizes to diameter?  I see that
the strength varies from 7.5 to 9.5 lbs per size #.  So the
diameter should be roughly proportional to the square root of the
size #.

Also, how messy is the tar, especially at high temperatures in the sun?
Does it get all over your hands when handling the twine?  Does the
tar tend to form a solid ball around knots making them difficult to
untie?

I will say that tar sounds like something that should be bulletproof
w.r.t. UV if it stays put.

The price for 220 lb twine works out to slightly over 1 cent/foot.
Baler twine is something like 2/3 cents/foot.  So this is very
cost effective given the additional UV protection.
