I know this question has been asked-I searched the forum and read anything I could on it. But... How do you remove the trim from around the rear window and then reattach it? Which piece comes off first? I noticed some rust around the bottom corners. If the rust does not go through the channel, can I just wire wheel it out and carefully prime and airbrush the paint back in the groove? This is an original paint car and I dont want to do more than necessary to stop the rusting. Thanks for any advice.
