I am not sure why but my dash pad and my A-pillar pads are really sticky. My guess is its some residue left over from some product used on them years ago. What should I use to try to clean these that wont take the color out? They are black. Also on the dash pad there is a 1" long split. Is there a way to repair this? I haven't heard anything good about the repro's so I want to try to salvage this one.
