leadcore

when tying up leadcore , should you 'seal' up the sheath end somehow or just leave it frayed . wouldnt want to weaken mono or flouro with harsh chemical..

I used a water based siliconized caulk to make it slip thru the guides better. The pic is of a willis knot; before and after.

I too have never sealed. It might pick up a little extra cottonwood seed with more fray near the knot.

I have never sealed it up and not had any problems.

A small drop of super glue applied to the leadcore end is what most do to prevent fraying of the sheath.

Good Luck
