That definitely helped with my very rusty SEC rear window situation, for a while. I think the stuff I used started to get less good after a couple years. Definitely helped though!I'm posting again the rear window fix I did right after buying my SEC, the glass was leaking into the boot and while I don't know how bad the rust is in there (it's not as bad as others I've seen here) it has been arrested. I got a couple of tubes (I suppose you could use a gun) of black rubber RTV sealant, snipped the screw-on tip to the next smallest opening at a slight angle and then flattened it a bit. Carefully lifted the rubber glass seal to get the tube tip in between and went completely around the glass, any excess will ooze out. I then did the same between the window rubber and the paint. The car sat in my garage, and where I keep her parked, so the Summer heat could dry any moisture in there from trips in the rain (not many of those but if it rains while I'm out driving her . . . . . . ) Make sure there are no gaps in the RTV and a good bead is applied, any ooze can be cleaned up after it sets. I've had no water in the boot since doing this
Yeah, bathroom silicone likely has no UV protection. The way I applied the RTV it gets no direct sunlight and it actually "glued" down the window rubber to the glass/paint, so far no leaks, even with the multitude of car washings and the few times caught driving in the rainThat definitely helped with my very rusty SEC rear window situation, for a while.

For future readers, don't make the same mistake I once did and use bathroom silicone. So much rust!! Automotive stuff only.
How annoying. I got extra sealant put in my SE, he warned me it could goop out somewhat for a while in warmer weather, butit didn't do that too much. I was pleased to see it was more like mastic tar stuff. I used some expensive stuff like that to refit my 2cv windscreen, it stays goopy a bit, awesome stuff and my windscreen (always leaked even after professional replacement in fact especially bad after them) literally doesn't leak a drop now.I had a perfect original rear windscreen and had it removed by a glass company. I took the Mercedes with the rear glass out and had bought the rear panel and rubber gasket/seal from Mercedes about 3 yrs ago. Carstar the body shop that mostly does insurance jobs and whose owner I’ve known since I’ve been in the business did a wonderful job. The catch is though the glass company when reinstalling the glass did not use any kind of silicone sealant at all. I only found this out two months after installation when the rear glass started fogging a little on the bottom corners. Consequently I had the windshield seal siliconed by another glass company, but the fog remains. I’d love to take a baseball bat to the knees of the installer if I ever met him again, he ruined a beautiful original windscreen because of his incompetence.
I'm a good boy these days, stop at traffic lights and everything 😊Daily transport 9spd Giant DH Comp downhill bike
@ianrandom daily transport when living in London was a three speed from Exhibition Rd (SW7) to Hyde Park, around the Serpentine, across Park Lane to Grosvenor St. and the (then US Embassy). It was faster than taking the bus or driving. Once ,going along the Serpentine, I spotted my first mini-skirt. My head swiveled around, my bike continue right over the edge into the pond. Another time, a bobby stopped me for riding "no hands" and threatened me with a ticket, but they were good guys and he didn't Those were lovely days.
