Silicon for rubber seals

[Hellequin]

I think I need to blast my rubber roof and window seals with silicon. Never done this before, what is a good silicon to use?

Use gummi pflege or similar, perfect for roof seals

I tried Gummi, didn't think much of it.
Got 2 sticks chucked in cupboard.
If the rubber is dry and chalky, as i have seen a few, i use https://groceries.asda.com/product/car-cleaning/triplewax-tyre-shine-foam-cleaner/1000098516624
Paint it on the rubber, let it soak in, them wipe over.
Don't let it touch plastics though.
Then i used https://www.amazon.co.uk/Triplewax-TBR500-500ml-Bumper-Shine/ on rubber and all gaps in the dashboard.

Then i use cheapo Lidl beeswax polish on everything, rubber and paint work, stops the roof squeaks.
My rubber trim is like new after 13 years.

Any silicone-based stuff is fine TBH. I use some Auto-Glym stuff only because I had some lying around. Works fine.

As long as it's not petroleum, or alcohol, based. That eats the rubber away, apparently.

I've got a generic tin of silicone spray from Halfords or Toolstation. Stopped the hardtop rubbers squeaking on the bodywork nicely.

With cans like this it's usually best to spray onto a bit of paper towel or cloth and rub in to avoid getting it on paintwork as they can be a bit indiscriminate otherwise.

Very surprised to hear that, I've been using it as long as i can recall and it keeps the rubbers perfect, doesn't leave marks on the paintwork and help with windows not sticking in cold weather - and what i appreciate the most with this is that it actively rejuvenates neglected rubber seals too per my own experience. That said, we all have our own view and preference, as long as the seals are maintained thats the main thing..

One problem the rubber they used to seal roof is some kind of synthetic. Looks slightly rough and green mold seems to grow there if you don't clean at least once a month. I wondered whether a rub over with bathroom anti mold might stave it off, worked well on a north facing caravan awning.

I try to use gummi pflege, but the 'stick' I have has a really annoying sponge end to it that keeps falling off when I go to use it at more than an angle of 90 degrees.

Found BMW's own (liquid) 'Gummi Pflege' very good. That said, haven't tried others.

Wipe all rubbers, and there are plenty, with damp cloth to remove grit and then apply thoroughly with bare hands.

Yep, Gummi Pflege, works on my wife’s Focus CC. Volkswagen Eos owners were having serious roof leaking problems a while ago and they used it to sort out the problem. Softens and plumps up the rubber apparently :roll:

Thank you. Will try it on my wife's Ford Sieve ... er ... Fiesta.

Ordered the Liqui Moly Gummi Pflege, will report on how it goes

 

[flybobbie]

Well next time i will give the Gummi a second go, especially the seals across the roof, they always dry out..
Might as well not go to waste.
And yes that sponge thing is annoying.

I'm going to go against consensus and say I've always found Gummi Pflege to be too watery and pointless on cheap recycled BMW rubber. Doesn't last long at all.

Decent silicone grease will do a much better job. Try Granville 0073A silicone grease for great results. Apply it with a round detailing sponge or microfiber cloth.

so, I have used the Gummi Pflege on the rubbers and they seem to have a better 'feel', so I am hoping it has worked

NO dont put anything silicone based anywhere near your glass, once it gets smeared into the door and seals you will never get it off your glass again. It gets resmeared every time you lower and raise your window. In addition its sticky and holds dirt and dust so todays fix becomes tomorrows problem
