Sealant for automotive purposes?
Discussion
Folks,
I’ve had a bit of water ingress with my E Class coupe around the rear window area. Looking at the boot trim on either side there is lots of crud underneath so I want to remove and refit with a small bead of silicone. The rear windscreen is bleached in the corners as well so will try a bead on that and if it fails bit the bullet for a remove/refit.
Thinking normal Dow Corning 785 clear, unless anyone has better suggestions?

You've got the car in front of you so know what you are looking at, but I had a leak on the boot of my E-Class when it was about 12 years old and on closer investigation it was due to some rubber parts that directed the water flow around the boot lid had perished and a tiny tear opened up.
Turned out to be a common issue, the bits were not expensive even from the main dealer, and surprisingly easy to replace. Worth having more of a poke about that area and seeing if the leak is due to something easily replaced.
ETA if you do go the silicone route, Dow Corning is about as good as it gets. Fernox LSX is a little more resilient but it's a bugger to use (I've never seen it in a cartridge) and virtually impossible to clean up spillages.

Anyone used "Captain Tolley's Creeping Crack Cure"?
Yes, used it to good effect on a leaky MGB windscreen - the frame surrounding it was leaking through, weather tight now.carreauchompeur said:
Brilliant, cheers. Can use Tiger Seal for a few bits on my motor home too so that May be a winner.
Another vote for Tiger Seal, although you want to be absolutely sure you don't want to remove it! Use it sparingly for any trim that might want to be removed later.donkmeister said:

Thanks for this. I think probably first option would be to get windscreen resealed.Turned out to be a common issue, the bits were not expensive even from the main dealer, and surprisingly easy to replace.

Basically, boot is dry but foam under parcel shelf gets damp. I’m fairly sure it is the rear windscreen seal which wicks moisture inside slightly. Removing and reseating boot trims can’t hurt though.
Will hold off on Tiger Seal given comments below!
