Rev is absolutely correct ,just take a very fine paper and scuff a small portion of your shaft where the fletching's will be placed. Then clean it off with an alchohol before you apply your fletching's. It's easy to apply too much glue ,so just take a cloth with alchohol on it and wipe it doen the edge where the excess glue is ,just don't soak the rag ,a little bit will do the job.
