Squirt! No! Not what you’re thinking, you perv! I’m talking about the amazing Agent X from Rio, the line dressing you spread on your line and that makes it slide as if it were new. This is the perfect gift for Xmas if you don’t want to spend a lot…less than $10. It’s even better if you get it with the Wonder Cloth. When I’m salt water fly fishing I clean my lines every night with it and I promise it’s awesome. I could never go fishing without it! Works fine for salt water or murky waters.
