They must have improved it quite a bit in the past several years.

I tried some from the company that originally brought it out (name escapes me), and also Bohnings and had nothing but trouble with it, no matter how long I let it set. the ends would start to curl before the glue (even instants) would set.

I'll stick with old fashioned-glue for my old-fashioned feathers

BTW for anyone interested;the new Fletch-Tite Platinum RAWKS! A little bit thinner but the bond is stronger, and sets in about 1/3 less time.
