Cerbera door seals

[ceejay]

Looking for advice on how to fix door seal problems and minor water ingress in the lower front corner of each door. These seals were recently fitted and have kinked so water gathers and creeps in. I’ve seen some that have the seal cut away but I’d rather not do that. Has anyone successfully unlinked or straightened? Other remedies? Car is garaged but I’d like to use more this year now the engine has been rebuilt. TIA, ceejay.

My joint is half way along the bottom edge, not up the door. I've not got kinking, but I guess that sometimes happens.
Can you warm that bit in hot water to make it more pliable and smooth it out

I'd guess having the ends there will mean any water getting into the seal will run down the inside of the seal into the car. Shouldn't there be a piece of rubber tubing inside the 2 ends joining them together?

Mine had the join on the vertical section from the factory (2001 car), but it does make sense being on the bottom in the middle. I think I’ll try heating the seals to see if I can form them better or maybe put some kind of drain in there. Failing that I’ll get some new seals and start from scratch .Thanks for the advice guys.

It was normal for TVR to put a crimp on the bottom section of the seal to allow water to run out. Maybe the person who fitted the replacement didn't know .Personally I wouldn't have the join there, just asking for trouble as water runs down the inside of the door.

Trying a few different ideas with mine: changing from the vertical to the horizontal joint, a tube inside the seal to keep the shape, adding an extra rubber piece on the A pillar, & a different seal from a Mk6 Transit. So far, mixed results. On the plus side, no leaks at all when moving. Mostly, water enters when standing. Best fix so far; keep the d4mn thing either inside or moving...

Will update if I ever get to the bottom of it...

It doesn't look like your door has the 'P' shaped seal on it. When closed this butts up against the outer front edge of the inner seal.

Does anyone else have these p shape seals on their doors? Looks like TVR had a few goes at sorting this. Who knew door seals could be this interesting!

Mine doesn't, & it's one of the other things I've had a try with. My suspicion is a combination is probably what's needed.

It might be because mines a Mk1 and it could be that Mk2's don't have the 'P' seal? Is yours a Mk2? I believe the main seals are wider on Mk2's.

Also, you can rejuvenate the seal by apply liberal amounts of oil and letting it soak in. I regularly use silicone spray on the seals and they regain a lot of their original supplety. Silicone spray doesn't leave a residue on the rubber once dry. They just look like new :-) This might help remove/reduce the kink. It also has a side effect of helping the glass slide up and down.

You need to apply multiple coats and let the rubber soak it in between applications.

Talking of seals, I presume mine are fairly old now but they still keep it dry inside. That being said, the wind noise inside is fairly significant - is it possible to reduce it by replacing the seals or is it part and parcel of driving a fairly flimsy machine?

Mine is a Mk2: I've used new seals, so pliability shouldn't be an issue. I think the basic seal is the same on both, it's a Corrado door seal, VW didn't change it. It can depend on the angle the cars parked at, & the intensity of the rain. There's a company that makes seals for industry near me, I aim to go over with the car for a chat, but life keeps getting in the way.
