rainwater entering somewhere, just haven't been able to find the spot.

Tom,
A sloow seep can be hard to spot.  It's most likely to occur anytime water
is standing on the outer surface of the car, especially when covered with
melting snow/ice.  One way to spot the location is to shove dry paper
towels up against any possible leak location.  Check the towels after a
night of rain, etc to see if any are wet.  Often evaporating water will
leave a light powdery/crusty film, especially noticeable on the black
rubber window seals.  One of the best sealants for the rubber window seals
comes in a tube and is called "flowable silicone" ... it sets up very
slowly and will seep into the same pathway the water had been following.
good luck,
Dave C.
