that was my useless guess.... not knowing WHAT glass....

get some clear silicone sealant in a squeeze tube at wal-mart. gently pry the rubber around the windshield away from the body and put a long bead of the silicone down into in the groove. start on top in the middle and go completely around. do not use a screwdriver or other metal tool to pry the rubber or you will scratch the paint. if you see detritus in the groove, brush it out with an old toothbrush and a hand vacuum before you put the sealant in. do not go overboard with the sealant, trim the excess off after it sets up.

if that does not work you are going to have to pull the panel which covers the wiper assembly and find and fix the leak in that well.

dealing with a problem like this is a clue as to why you should never, ever get a car with a sun or moon roof. they only leak always and forever.

just use the gasket.

Try using a long piece of dental floss, like a saw, all the way around until you cut through the silicone.

Is the seal damaged - if so replace it as this is the best solution, if not see below -

This is a common problem caused by the rubber seal. Remove the seal and then put a small bead of silicon rubber sealant all the way around the metal lip it fits on - then replace the seal. Next when the sealant has set, clean the boot lid where the seal makes contact and also the seal itself with a silicon spray polish (Mr Sheen) this should cure the problem if the water is entering via this seal. Also make sure that the gully around the boot lid is clean. If this cures the problem, every few weeks clean and treat the seal and lid with silicon spray.

Hope this helps - good luck.

The silicone most be 100% silicone appropriate for aquarium use. If the sealant tube did not say this on the tube it is not safe for use in aquariums. They sell this type at pet stores that sell fish. Also make sure you use acetone to clean surface before applying sealant.

lift rubber edges and apply clear silicon sealant under edges let cure hose with water to test, if leak then seal edges of glass with eurothane sealant, not silicon will rot in sun within year

You need to seal from the outside edge and I would use a clear silicone made for use in wet conditions. It wouldn't hurt to put a bead around the bottom edge as well.
