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.

Proline with overhang marker

Bought two for my son and myself… super fast delivery and have to say, I have only used Sunday fly lines since they first came out. Put yards onto my casts. Thank you

John Andreou (Cwmbran, GB)

It's pretty good but a very small can for the price. I put some on a clear intermediate line and had to wash it off with soap because the line wouldn't sink after applying it. I find Autoglym works every bit as well and I've had an aerosol can of that for quite a few years

Marco Cecala (Yarnell, US)
Works great!

I tried this product as I find liquid treatments a bother to use. It went on easy and perform great. I build custom rods and always tell buyers to get this so they can make the most of their investment. Line stays cleaner and shoots like it came out of a cannon!

Nigel Wood (Stoke-on-Trent, GB)

With targeting carp I matched this with the line , my hook rate has doubled as no drag when lifting in to the fish , also the presentation is smoother and does not spook the fish as it floats on to the water

Another awesome product and must have

William Wilson (Preston, GB)
