Hi all, our 2008 4Runner SR5 has developed a weird problem. The plastic or rubber rain cover over the rear liftgate latch is torn and sticky and black gooey stuff gets on your fingers when you operate the latch. Has anyone heard of or experienced this problem and if so, what did you do to correct it. My wife is nagging me to fix this and I don't want to go to the dealer. Thanks for any input or ideas Glenn
