TroutLine Perdigon Resins Medium Thin and Ultra Thin. 22 September 2023 

In summary, TroutLine offers two dedicated UV resins for crafting perdigon flies, both of which exhibit lower viscosity compared to traditional UV resin.
Why?
1. to facilitate easier application,
2. to prevent the entrapment of air bubbles,
3. to enable smoother and more efficient spreading across the nymphs’ bodies.

Ultra Thin, which is twice as thin as the Medium Thin Resin, is ideal for medium, small, and ultra-small flies, as well as for reinforcing the bodies of dry quill flies.
The Medium variant performs exceptionally well for flies ranging in size from #10 to #18.
