I don't quite understand what you are trying to accomplish.. you are trying to remove the glue, but are you keeping the tint that is on the car or not?
If you are trying to keep the tint, the DO NOT use Windex or the SOS pad. Use a soft cloth, soap and plenty of water. Everything I've read says to never clean a tinted window with windex and you don't want to take the chance of the pad scratching it (I'm sure it could).
If the tint is gone, then you can use the Windex. Probably still not a good idea to use the SOS pad on anything, because a soft cloth will work fine.
