and they are silent so far. My car was real bad prior to the new seals, so any improvement seems monumental. The "Kent" product mentioned in the responsive post below is "Kent-Moore" dry lube and it is available at most GM dealers. It's worth a try. Rule of thumb for these cars is not to apply anything gooey or wet to the door seals. It will be a step in the wrong direction, even if it makes the annoying creaking go away for a week. Hopefully your dealer will not install an inch long scratch on your fender when they install the new seals, like they did for me! Isn't that always the way, though? Fix five things and create at least one problem while you're at it?
