If using shrink tube to protect knots is a step too far, then the Tronixpro Knot Protector is the next best thing. Designed from clear silicone tubing, the knot protector will slide over the knot to the lead link, to the top rig swivel and the knot to the link on the shock leader. The supple silicone will keep the protector in place and is ideal for streamlining rigs to stop weed and lighter, longer hook snoods getting tangled in the knot.
