I wondered because WD40 is pretty good at removing sticky labels. I have long used it for that purpose.Yes,……“all the rubber weatherstipping, window-seals, door-hinges and latches, hood-hinges/mechanisms…etc etc….. have been LUBRICATED and all squeaks have disappeared.”
All my decals are in excellent condition since 1996 mfr) except the one on top of the left fender which explains ground-speed vs gear-selection…. which is worn/faded a “little-bit” primarily due to abrasion/sun because of its’ location. (it gets tools/stuff/brush/etc scrubbed-across it).
