My Dad runs a Waterfowl Outfitting service here in Maryland. He and his partner flocked over 100 geese heads and they look great. They made it through all of last season and will need a few touchups, but they seemed to hold up pretty well. But when he had half done/half unflocked and we were sitting in our blinds waiting for the honkers you could really tell a difference betwwen flocked and unflocked! Hope this helps.
