I got my backpatch signed a few years ago now, and it's faded to the point that you can barely tell anything's there any more. I'm gonna see if I can just go over the signatures again myself/get the band to do it again tonight (though the bassist's left, so I'll need to do that one myself anyway), but is there any way I can make them less prone to fading in the future except for standing at the back at gigs and avoiding any human contact? XD
