If the glue sets up in 15 seconds, it most likely is a "cyanoacrylate-based glue"; gel type in your case.

I know that some say they have good results with cyanoacrylate-based glue, but I did not. I try to be very precise when I fletch arrows -maybe an overkill at times, and I need ample working time before the glue sets. Additionally, I use an large bead of glue to set the fletch in a bed of glue. I then wipe the valleys in manner that cleans the glue from the valley and folds some of the excess up and onto the rail of the fletch. I tried this with gel cyanoacrylate and I went bongos and found out how vital having separate fingers is.
