In this Fly Fishing Special, I have tried to completely elaborate for you the topic of today's so many popular UV varnishes, resins and glues, which for me represent a kind of symbol of the 21st century in the fly tying. At the same time, thanks to this topic, I returned a bit to my original field of chemical engineering, but you do not have to worry - I tried to eliminate the scientific approach and not overburden the article with it, but rather enrich it! ;-) If you are interested in this topic, I will be very happy if my next publication becomes a source of useful information and inspiration for the moments spent at your fly tying vice - when inventing new patterns, or when innovating the existing your favorites flies!
