I had my dealer fix this problem. After washing my car,
the rubber surrounding around the rear windshield
would retain water. After few months owning this car,
I noticed part of the surroundings started to fold inwards.

It doesn't look very good, and is pretty annoying after
awhile. The techs told me they had to remove the
glass to replace the surrounding. So instead, they
used some sort of silicon sealant to prevent
the surroundings from folding inwards and retaining
water.

Well... its' been a few days, but I don't think the fix will
last long. Water still gets trapped inside.

I believe the material is too thin, and warps easily because
of water trapped inside and heat from the sun.

Anyone has this problem?

(Hmm.. since when did I become a "350Z know it all"? )
