Hi there I am wondering if your heat shrink tubing would be suitable to stop chaffing on our mooring line rope. My boats mooring line chaffs and wears against the fairlead where it is attached to the boat. The rope diameter 32 mm, so guessing the 52 mm tubing would be most suitable with the most wear resistant coating/material.
Any suggestions would be great fully received.
