Very carefully!



Most trim will have fold-over tabs on the end to release them, or will be embedded into rubber gaskets (like the windshield). On my old 2-door wagon I didn't have stainless on the door windows or elsewhere other than windshield, so I'm not sure the answer to those particular pieces. I would be looking at the ends for tabs, or they may be snap-over the edge pieces like the roof gutter stainless. Taking some good photos of the parts you are working on may help to figure it out.
