Mucilin Dressing - Red Label
This stuff has been around since Hardy started printing catalogs! Ahh… the classic English Floatant.
Available with silicone (green) or without (red).
Mucilin is denser than most other formulas, which makes applying it less messy when you are coating a fly or your leader. Another good product for greasing your line, leader or tippet to get it to float.
It has a loyal following of anglers around the world and still remains as one of the best in the business after all these years.
