How do you fix/remove rear window surround trim?

Sounds scary. This is the kind of body work that sounds best left to the professionals..





Gasket. Check. I'll get one and expect the worst.. sounds like a vintage body shop may be the way to go with this job.. and expect a decent bill at the same time.. Thank you everybody!
I think this is getting blown out of proportion. It can be a simple job. I see no reason to put in a new gasket. New gaskets suck by the way. Nobody wants that job. Does the window leak? Is it original paint. It doesn't look like a rust bucket to me. @Mark Wainwright
