I’ve used Sink Fast on my sinking line for several weeks now. The line stays dry and performs better in saltwater. It’s easy to apply and doesn’t leave a residue. My casting accuracy has improved noticeably.

The product works well for cleaning and protecting the line from sun damage. I apply it before each trip to the lake. It feels smooth and doesn’t affect the line’s weight or sensitivity.

After using Sink Fast, my sinking line no longer floats as much. It’s more reliable in windy conditions. The non-toxic nature makes it safe to use in my outdoor setup.
