Got my sunroof out and headliner down. Cassette looks to be in ok condition, the passenger side rear drain hose looks to have some junk in it. I also have to split the sunroof itself to deal with some internal rust. Looks like the glue BMW used for the headliner foam also was a little corrosive, the overspray that hit the rood has caused some surface rust.
Second pic shows the only significant rust I can see on the roof itself. My current plan is to stick the sandblaster in through the various holes in the sunroof cassette and get it mostly cleaned up, then I will neutralize the rust and coat with por15, which should stop anything from occurring in the future.
Headliner foam ripped while being removed, so I'll have to replace it. I think I'll stick dynapad to the cassette and trim around the sunroof hole with an exacto knife.
