This stuff has been around since Hardy started printing catalogs! Ahha | 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.
