I’ve used Loon Sink Fast on my sinking lines for several weeks now. It makes a noticeable difference in how the line performs in saltwater. The spray is easy to use and the line feels smoother after application. No issues with residue or damage.

First time using this product and it worked well. The water-based formula doesn’t leave a sticky feel. I applied it right after opening the new line and noticed better sink rate in the water. Would recommend for saltwater fishing.
