100% non silicone cosmetic grade line slick and floatant designed to maintain the life of your fly line and increase distance / buoyancy / accuracy.

40g recyclable metal tins.

What it's for

    • Making a PVC, Polyurethane or Silk fly line slick
    • Making a fly line float higher
    • Increasing the life of your fly line
    • Protecting the varnish on cane / bamboo fly rods

A non silicone cosmetic grade line treatment that soaks into the multifilaments of silk fly lines and protects / slicks pvc and Pu fly lines. Why? Reducing friction creates tighter loops, gets further distance and creates a barrier between water and the line, meaning quieter, easier pick ups and higher floating lines. Some silicone treatments are too thick, some are too thin, some attack the varnish on rod blanks. Sunray LINESLIK doesn’t. Being cosmetic grade we actually use it as lip balm and hand moisturiser too. You may laugh but when you’re in 60kph winds and / or blazing sun, you’ll be grateful for it. We have been, many times. 

Fly Rod Warranty

This guarantee is limited to the Original Purchaser and is not transferable to future owners. If during 3 years of the original purchaser, the rod should break or fail, for whatever reason, simply return the rod, invoice, sales receipt, or proof of purchase and we will replace the rod or damaged/faulty part by return.

If within the first 36 months from the date of purchase the failure is due to a manufacturing fault or material defect, then our normal manufacturer’s guarantee will apply and the rod or part will be replaced free of charge, with the relevant handling/postage fee returned. Fees will apply if the failure was due to user error.

Should the rod in question be discontinued it will normally be replaced with a new model up to a similar value, or there is the option to ‘trade up’ to a rod of a higher value, by paying the handling/postage fee, plus the difference in value between the two models. Please note however, that in the case of discontinued models, if purchased in a clearance sale, the maximum value covered by this guarantee is the price paid and not the original RRP.

Not sure yet

Only fished once since purchased. Line went out well but need to use regular to determine if Lineslick is worth using.

Glomis (Tychy, PL)
Proline #4 #7 +linesilk

I have two lines from sunray and they shot like a rocket,
"Less means more" its all you need to know using them:)

For sure will get another ones. They ale from now my first choice.

Linesilk helps a lot to keep lines in minut condition with no doubt.

ROGER DODD (Joliette, CA)
Sunray Lines and Linesilk

I have now purchased 3 different lines from Sunray and to say I'm impressed is an understatement. I run these lines in #6 and #8 and can't fault them. After 40 years of casting a fly I now cast further and with more accuracy. Here in Canada we fish streams in tight quarters within heavy bush situations. The ability to roll cast these lines makes getting the fly to the spot much easier.
I have helped in teaching casting to members in our Club and once we can meet again due to the pandemic, I will be demonstrating these lines to fellow members.

Lineslik Line Treatment

To be honest, I was thinking, here we go, another gimmick being pushed onto the fly fishing community and another thing to wedge into my waistcoat. I didn’t appreciate perhaps (a) what a difference it makes to the casting (b) only takes a couple of mins to prep your line ( c) once prepped, there’s no need to carry it around. My thoughts now are that I’ll be keeping Lineslik maintenance of my lines up, it can only extend the life of them and improve my distance too. What’s not to like.
