Does anyone have a problem with their oakleys unobtanium rubber? I have a Ducati Crosshair that is rarely used and its been seating in my oakley shelf for a longtime, I noticed that even though I rarely use them they produce some oily liquid. I know that this only happens when you use your oakley almost everyday like my Wiretap RX and soon after it will crack. I called oakley and they said that they don't have replacement rubbers for Ducati Crosshair because its been discontinued for a very long time. Can someone give me an advise on how to prevent this from happening or does anyone of you has the same experience????
