I have gone through a number of adhesives for fletching arrows, from Ducco cement to cyanoacrylics of every stripe, and now Bohning's Fletch-Tite Platinum.
Last winter I was pleased with this Fletch-Tite, but today this stuff is worse than useless! It claims a 5 minute clamp time but I am setting the timer for 10 and the stuff is still not setting. The only thing I can think of is that the glue does not like hot and humid weather.
What is your experience? Has someone else had trouble getting this to cure and if so, what were the conditions?
