Need suggestion. Windshield leaks across top. It is fairly new, but
put installed in another city, so I can't take it back for warranty.
Trying to figure out the best way to seal it. I was thinking aquarium
silicon sealant, but I am worried it won't be "sticky" enough. Is
there something better?
Is this a flush glued in windshield? In any case, if this was paid for by
your insurance company, you might call them and ask them for assistance in
getting someone local to fix it. Otherwise I would just bite the bullet and
bring it in to a windshield place and ask them to repair it correctly. It
probably won't cost much.
As suggested, I would recommend trying to have it repaired by a auto
window shop first. Find out how much and or see if you can really get the
warranty honored or if the insurance company has any suggestions.
Other than that if you end up doing it yourself, you can buy either the
aquarium stuff or the stuff at the auto parts store. Believe me the
aquarium stuff is strong enough, it will hold aquariums together after the
fill them with water. It is strong.
Another thing to consider is that today's auto bodies get a significant
part of their structural strength from the glued-in windshield.
A poor job of bonding the glass to the body defeats that.
IMO,leaks indicate a poor job.
I've had to cope with this problem several times over the years. The
bottom line is that once it starts leaking, body rust is involved above
the windshield. So you have to go to a body shop. But they will tell
you the windshield has to be removed and will probably break, so it must
actually be replaced. I used a local technical vocational high school
and they did an excellent job for about a third of what local body shops
Unfortunately, I've had consistent problems with our Dodge Grand
Caravan's windshield leaking at the top. After some attempts of repair
by the dealer and the a local auto glass shop (by back filling), I had
the shop replace the windshield.
Over time, a leaking windshield will cause the pinch weld on the body
to rust (see Stubby's post above). This can be a major problem as the
windshield provides a fair amount of structural strength to the
vehicle. This is where a body shop may have to be called upon.
Good luck, as this can sometimes be difficult to fix, even with the
nessary body work and new glass.
Auto parts stores sell very runny windshield sealers that will drip
into the leak. Loctite has one based on silicone rubber, while 3M's is
crystal clear. You'll need to remove the windshield trim to make sure
it reaches the leak.
I've replaced 3 glue-in windshields myself and can't understand how a
halfway decent job can leak at all, unless the car was driven off
before at least twice the cure time for the glue. But for the glue to
stick well, all the surfaces have to be made and kept 100% clean, which
is why glazers are supposed to wear gloves while handling the glass.
Contamination can be so harmful to the glue joint that it can be
possible to push out the windshield by hand, and a windshield not held
firmly in place can be very dangerous in a crash since the
passenger-side airbag relies on the windshield to hold it in place.
