I am having an issue with my Winn Grip of about four years old disengrating in my hands, leaving a crumbling dust in my hands. Just checking if this is isolated or a sign of things to come. I have several rods that I have built over the last couple of years with them and this the first one that I did. The same thing happened to my Golf Grips....not a big deal on golf grip easy replacement not so much on rods.
