Ok....my new Rio Selective trout floating line is starting to sink at the tip. The line has a factory "Welded loop", thats supposed to put an end to this sinking, but I've noticed that the loop is splitting apart where it is "Welded" to itself. I clean the line properly, and I use "Glide" to dress it after I've cleaned it. Can anyone suggest a good sealant for the end of the line that will not make it become brittle, or stiff? I'm thinking that the water is "Wicking" up into the line and therefore making it heavier that at the start of my day, causing it to sink. Any help is greatly appreciated on this issue.
