I posted this in Wheels but recieved no response...maybe this'll help. I have a 92 400E. The front wheel wells (fenders) have already been rolled (not by me). Did the 1 previous owner do this or did it come like this from the factory? Also...When I roll the rear fenders, do I need to use that darned tool? I have access to all other body tools except that one that you attach to the wheel to roll the fender.
