Just got done replacing the weatherstripping on 86 Firebird with T-Tops. Removed old one, cleaned up all the old glue possible, use wire wheels on the drill, so I even had to touch up paint where it went down to the metal. weatherstripping went in smooth everything seemed to line up, doors were tight on new stripping and tops have a good bead between them and car. Let the car sit for a week, didn't open anything to let dry and set, tested it today and I have water coming in at the driver side Sun visor, where it pivots.... I have no idea where to start. Any Ideas?

I'd also recommend reviewing your install method with what's in this manual, if you didn't use it. It's very helpful as it shows all the materials needed, and precisely where to apply them.
