## Customer Reviews

### ⭐⭐⭐⭐⭐ I can see why this isn't sold in stores
*by L***D on December 10, 2012*

This stuff is GREAT. The waterproofing that this stuff applies works so well that a quick strip of the fly line can sometimes cause the smaller flies to go airborne! Bigger and heavier flies, like a #10 muddler, remain buoyant even after catching a few. The first time I applied this I dumped a mixed bunch of flies into the container, and even though you are only supposed to apply to brand new flies, the repellant totally worked its magic on even the dirty ones. One application to approximately 40 flies still left about 7/8 of the container full so one jar will go a long way. You can try economize by draining the excess off newly coated flies back into the container but the payoff is minimal.The flies that get coated are good for MUCH longer than just the ones exposed Loon floatant. In fact, ever since I bought this stuff I have had no need to even take the Loon floatant with me. After using it once I can definitely see why the big fishing stores choose not to carry theHydrostop because if they did the store shelves would be FULL of regular floatant year around.

### ⭐⭐⭐⭐⭐ Better then advertized!!!
*by D***L on July 20, 2019*

Works as promised, even better! Fished for 2 hours with the same fly. It never sank. Even in fast running water. Good by GINK! This is better ,easier to use, and no mess.

### ⭐⭐⭐⭐⭐ Works Well
*by J***H on September 12, 2013*

I used this for a weekend of fishing and it performed quite well, it wasn't perfect, but it was pretty good at keeping my flies afloat. They did eventually sink a bit, but very little, if you took the time to dry your fly between a majority of casts you will probably be golden.
