Absolutely agree with Gary. I’ve spent the last two years playing around with silicone oil in various guises. We were selling Shoot which was an silicone compound less viscous than water. Pure silicone liquid is more viscous (ie less runny than water). Finding the right mixer is important because you don’t want your line to fuck up.
Buying industrial sizes quantities from China looked like an interesting option. It would bring down prices AND give a greater margin - enough to make wholesaling a possibility. However it also means that I have to buy industrial sized quantities (200KG!) which makes wholesaling not only and option but also a necessity!
That’s not really where I want to be
So we will go back to the original product with small quantities and smaller margins. The only drawback with this stuff by the way is that if you need to change rings for rod repairs then your rod builder will have a hell of a time cleaning the blank. Otherwise the rings will slip again and again. But it’s a small price to pay for longer casts; unless you are the rod builder of course!
Incidentally line slick is very similar to fly floatant. It’s just differences in viscosity. In my research I have discovered everything from thick fly floatant suitable for the tropics to ultra thin shooting line silicone for the Arctic. I’ve also killed a few lines.
Something like this could/should revolutionise fly fishing but the general market is very traditional. Squirting silicone Shoot onto your line every hour or so is really Sexyloopers domain.
