Leg builder is a substitute adhesive for Tail Adhesive. At first I was hesitant to switch from Tail Adhesive but when I did I don't know if I will go back. Tail Adhesive can give hair a white tint. With angus you can't use black touch up paint to make the leg or Tailhead black at certain shows. I think that it holds just as well as tail adhesive and like I said in an earlier post you can pull through it with more ease. I totally fell in love with this stuff.
