They make a tool for removing the stainless windshield trim and back glass trim. It slides between the glass and moulding till you hit the clip and give it a slight pull down and it will release the trim. go all the way around the glass till its off.

It will help on the cost of a paint job for sure , as it will save time for the body man or painter to remove it all to get to work on the vehicle.

Just make sure you mark everything you take off , so you know where it goes . take pictures if need be.
