If it is not seeping or peeling off after attaching, the bond dried before you placed it. Yu can get accustomed to the attaching steps by practicing without dipping, at first. Just get the motions down as you pretend you are attaching. Once you have that "muscle memory" down, then you can dip and attach "for real."
Make sure your bond is very hot and "drippy,” a correct temperature of 174 degrees Fahrenheit. Re-dip 3/4 inch of the tip into the bond and get the bundle to the hair section quickly, before it dries. Do not scrape the dipped extension tip on the side of your pot before attaching, you'll scrape off too much bond. Just a little shake of the tip and it will loose any extra bond and will round it out for attaching.
