Superhydrophobic Coating

This is amazing. Plenty of fishing applications: flies, lines, waders, boots, rain gear, boats . . .

It leaves a visible film. Fly fishing applications are few. Don't do flies, lines, etc.

Last bit of the second video says industrial use only. Cool stuff though

Pretty useless stuff bordering on hoax for most advertised application. I've used several brands. It leaves a skim milk colored coating, gums up flies, and has about zero abrasion resistance. A light swipe with your finger will wipe it off a treated surface. The bottom coat is xylene, naphtha, methyl ethyl ketone, hexane and toluene. It is meant to etch just about any material so that the top coat (96% acetone, 2% hydrophobic silica "Frogs Fanny"and gum) will stick. You do NOT want this on your fly lines or Gore-Tex!!

I use the two part stuff from Rustoleum and it works ok. Like mentioned before not real durable. Leaves a frosted look and do not apply indoors!! Really noxious fumes. They now make a fabric coating that is one spray coat that a friend used and it works pretty well on coveralls and leather boots without significantly changing the color. Remains to be seen how long it lasts.
