Fritz I had posted this question earlier, I have a 10 year old film dipped High Country Ultra Extreme that is still holding up fine, the work was done by ColorWorks, yet one of my 2003 Duallys has the same wear that you are getting the funny thing is this too was dipped by ColorWorks as they did the dipping for Bowtech in 2003. I just purchased a new 2003 dual cam and intend on putting one of those Limbsaver insulating strips on this area to prevent it from wearing, I believe it was JeffB that said it was due to persperation from your hand which would make sense as I carry my bow with this area in the palm of my hand.
Good Luck
