Where is this water coming from?

[MericaMopar]

Anyone experience water coming in at the edges of the dash by the corners of the windshield? I can't seem to see where it's coming from.

It’s basically going in under the gasket hopefully not through a rust hole.

Weeping through the window seal likely.
I had a similar issue on a re install. The window guy was sure he knew what he was doing. He didn’t follow the factory instructions ( or the new seal instructions). And put clear sealer in the inner groove of the seal.
First hose wash the water went into the seal around the glass and out the inside onto the dash.

Thanks, looks like I'll be taking the trim off the windshield then.

I kind of suspect/expect a rust hole...

Definitely filled with a lot of build up of crap in there, going to clean all that out and reseal it.

Definitely some rust issues there, I’m surprised there’s anything left of the data tag. You’re about to open a can of worms but one that needs to be addressed for sure.

Lol funny you say that... It fell off while I was cleaning it up. I'm just slapping some rubber goop in there and calling it good ... This thing is clearly not a show car.

Sand, wire brush, maybe saw the rusted crap out, then get some Bondo and fiberglass cloth for that. I don't love plastic body filler, but in this situation, it will do what you need. FWIW, old washing machines often furnish nicely enameled, water resistant sheet metal that can be adapted to save portions of an afflicted car. I've found plenty atrocities on Mathilda, my '66 Newport, which has spent most of her life in Tucson, but alas, came here by way of INDIANA, a Rust Belt State in several senses of the phrase....

it was mainly, dirt, grime, and surface rust. Didn't find any rust holes, the data tag took the brunt of the damage.

That will only speed up the rusting process and make things worse faster. At a minimum you need to clean the area removing as much rust as possible, hit it with a rusty metal type primer and top coat it.

I agree that goop will trap moisture and make it rust faster, but I'll also say that wire-brushing and coating it isn't a cure either. BTDT and the rust kept coming back. Rust at glass is the worst, several layers of steel spotwelded together like a sponge.

IMO best thing to do is wire-brush it until it's dry/clean, leave it alone, and try to keep the car dry. Surface rust is actually stable as long as additional moisture isn't introduced/retained. Could put WD40 or kerosene on the area after a wash to try to chase the moisture out.

I cleaned all the debris out from around the window. I only applied the rubber caulk where the gasket and sheet metal meet, which should keep moisture/water out of the inside of the vehicle and right under the caulk. I don't see it trapping moisture there. Once all the grime was cleaned out, it looked a lot better, nice shiny original paint underneath....58 years of nature buildup, I doubt the windshield trim was ever taken off. The rust is actually really only by the data tag, which I dont fully understand because that's a near vertical surface...

The backside of the tag never had a protective coating of any kind so any moisture through the years that got trapped behind it would just turn it to rust.
