Has someone semi-permanently sealed up a sunroof? I have a 123 with the sunroof leaks from hell and until I find the proper pan for amanual sunroof, I'd like to seal the thing up (the PNW weather will take the smallest leak and make your car a mobile swimming pool). I know silicone will trap water and eat into metal if I use it around the sunroof. I do not wanna weld it shut since that would mean the millisecond I weld it, a new pan will drop into my lap. Also, I'd like to leave the sunroof option open for the next guy who buys the car. I was looking at getting a piece of sheet metal a little larger than the sunroof hole and gluing it in place. Is there an adhesive that will seal this thing up but can eventually be removed if at some time in the future the sunroof wants to be resurrected? Since headliners are running about $300, I can do a less expensive custom headliner until/ if the sunroof lives again. Thanks for any ideas.
