I used fletchtite for probably 25 years and then switched to NPV or super glue gel when they switched to platinum and had all kinds of issues. I’ve never had bad results with NPV though. I think they have fixed all the issues with the platinum now too. I have recently used it also with good results.
I hope so, but once a product gets a bad reputation, it tends to stick around longer than the glue (bad pun). I continued to use fletchtite on carbon arrows after it failed on aluminum, and never had any problem with it on carbon.
I don’t fletch many aluminum arrows these days, but recently fletched up a bunch for a tournament that required them, using NPV. The NPV held up fine during the tournament and practice sessions: not one failure. I noticed that the tube of NPV was getting old, and was afraid it might go bad before I used the rest of it, so have been using it on carbon arrows, with the same good results, making me wonder why I still continue to use fletchtite for anything.
