Re: Backing to fly line question?
Pliobond/rubber cement may smooth a knot and prevent slippage of not fully seated coils but adds no strength to a connection. I am not certain about UV curing adhesives which seem strength addative but I do know that gap filling, slow curing super glue like Zap-A-Gap is truley strong. We never want to INCREASE mass at knots by creating a "bead", rather we want to seal knots to prevent slippage or stripping coating off line core. Overlapping a bit onto the line coating may enhace adhession and onto the line tip/tail ,sealing the core from water wicking. Of course, a properly tied, multi turn (12 - 15) nail or Albright knot has good profile and can stand on its own...but a light treatment of strong sealent can't hurt.
