I just bought an 03 GT, the previous owner kept it in pretty good shape but in no way took care of it like it should have been. Mainly, when I was cleaning under the trunk lid I noticed rust under the rubber seal at the bottom of the window. It doesn't seem to be really bad but I want to stop it before it gets worse and try to clean it up. I'm assuming it may be somewhat common with the new edge body. Any advice as to what I need to use to stop and fix it? Any advice is appreciated. Thanks
