I buy my custom wraps for wife and me from Onestringer. I like to buy in quantity to get a break. That can be an issue if the unused wraps sit around for more than a couple years. I had the edge come up on a set. To solve this problem I wipe on a thin coat of waterbased polycrilic with a foam brush. Actually I got into this habit cresting the plain wraps I bought from them. Protection of the cresting. Since doing this, about 10 years) never had any wrap edges come up. Either Bohning or Saunders NPV or super glue works for fletching .
