Then the seals are filling up with water, because they are not seated properly or have decayed. Look at the seams between the seals, they must be TIGHTLY pressing on one another.
Look at where the seals meet (yellow arrows) if there are gaps, your seals should be replaced. Unfortunately, new parts are not available.

Any Roadster not kept in a garage and out of the UV will have issues like this eventually. UV is ROUGH on those seals.
My Graphite was outside the last four years of it's life and I noticed drips at times just before the car was lost in an accident.

Perhaps you can "build up" the ends of the seals with RTV or another compound.
