I use it on my bass rods and love it...I have never really thought about it leaving a residue...I do know that when I use it I get it all over the reel...I never feel anything on it. I have never smelt it or anything. I know it REALLY helps the ease at which the line leaves the spool. Really smooths it out..and really helps reduce memory...I also use it on my braided line. Just my thoughts..I love the stuff..use it on all my reels.
"But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord.” Joshua 25:15
