It rains, It pours, The Old Benz Snores (read: leaks!)
Dudes,
The black trim/sealant at the bottom left corner of my windshield is kind of loose. I can pull it back ever so slightly. When it rains, the carpet next to my left ankle (on the side) gets wet!!! Question: can I just get some silicone and seal it up that way???? Unless there's some crazy temp expansion it should provide a good seal, yeah? I want to do this Friday or this weekend as it's been on my mind and has been raining a lot lately. Any thoughts appreciated!! Thanks bros, Ben

Silicone tends to promote rust. You would be better off having the windshield gasket replaced.

Having the windshield gasket replaced isn't really an option right now. It seems like sealing up the looseness is way easier and cheaper--just need to find the right substance to do it with. Thanks,

I use it also, but the vinegar smell is acetic acid, so I do not use it on car windshields any more, after I found rust where ever the silicone was applied on an old Pontiac I had. I still used it for gasket making and also on the house, if needed.

Don't use silicone, but get some windsheild sealent insted. Any good autoparts store should have it, most likely 3M makes it.

I've had some success sealing rear windshield's. Clean under gasket , us a plastic putty knife pushing a denatured alcohol soaked little piece of rag, change often. Then apply windshield sealer from a chalking tube pulled along under the gasket. I mask both sides. My rubber seal wasn't all cracked and split, if thats the case just have it replaced.

windsheild leak
My 79 seal was cracked and splitting. Used a razor knife to remove the knarl, cleaned all the crud with soap,water,firm brush and putty knife. Then dried everything with my leaf blower, waited 2 days,masked both sides and sealed with black roof flashing sealer. Only took 1 tube, you have to have a caulk gun for this, and cut the tip at 45 degree angle @ 1/4 in - smooth steady pull, not too much, smooth withyour finger. Both my front and rear windsheilds no longer leak. I even sprayed water with the hose at high pressure to be sure. Note: this is only a temp. fix until you are in a position to have the seals replaced.

Butyl Rubber Sealant is a good alternative to silicone. It too needs a caulk gun to apply it.

Update: I ended up using some weatherstripping adhesive. Seems like it's sealed ok. Last time it rained my left foot got wet when I hit the brake. I think water is getting in elsewhere besides the windshield. Any likely culprits??
Thanks, JBG

What is wrong with silicone? How does it cause rust?
|

Silicone itself doesn't cause rust. Silicone sealant traps corrosive moisture as it cures which causes the rust. You can smell the acetic acid as it cures.
EDIT: rrgrassi already stated this in post #5
