Try Got2BGlued styling glue. It's not a hairpiece glue by design, but I love the stuff, and use it for my french lace partial. It cleans up with water, and leaves no residue. It is water soluble, so swimming or any water immersion is out. It takes a good sweat without losing its bond; I get about 3-4 days before a de/reattach. Search this forum for more detailed instructions about use, either posts by Leamon or Mr. New York. It's not for everyone, but I love it.
