I am new to the board, I have been reading a lot of your posts and responses and have found it to be very informative.Two questions,you know when you get into your car and you shoes rubs against the inside part of your door and seat area and leaves that dark tar like streak?Any recommendations on how to get that off?.I tried tar remover but it did'nt do a good job.Also the chrome trim around my doors are getting foggy,which cleaner dou recommend? Thanks all.
