SONAX 03400000 Rubber Care

I use this to "regenerate" the rubber seals on a convertible, with the hopes of preventing cracking and causing leaks. So far, it seems to really "re-moisten" the rubber, so to speak. The original Gummipflege that I used to purchase was made by BMW. That stuff is increasingly hard to find and when you do find it, it's insanely expensive. This seems to work just as well, at least it visibly has the same impact. It's easy to apply and on my wee car I've been able to treat all the seals twice over, with plenty of gummipflege left. If you've anything prone to leaking or with expensive seal replacements, this is a cheap bit of extender.

This is great stuff and the only one to buy to stop creaks from your BMW. Really does work, don't ask me how, but it does. Clean your rubbers well, let them dry, apply with the sponge top, like a shoe polish. Allow to dry. Go for a drive. Be astounded at the cheap fix. I was ages trying to locate the creaking and forums pointed to this stuff from Germany... I have applied it everywhere. Patio doors rubbers, window rubbers and seals. Instructions in German, but not an issue. a 5 year old would work it out. I tried numerous other products claiming to do the same, but they don't. This, however, certainly lives up to it's name. A bit more expensive, but you get what you pay for?

revitalised my SLK rubber seals - expensive really - you dont get much but enough to do a car twice for sure - a lot of seals on SLK. many leaks, not now, althoug I did use this first to supple up rubber, then some dow silicone grease to keep them supple / fill the gaps. no leaks or stemed up windows now. 5 stars if bigger bottle

Used this product to moisturise the door and window rubbers of my 16 year old Audi TT. Simple to apply and results are instant, the outside window rubbers were really dry and original natural black colour was restored. Other cheaper products produced an oily and shiny finish. The squeaky electric window that was driving me mad, was also cured!!!. I've only recently discovered Sonax and i have to say, that i'm very impressed with the quality of their product line. Instructions and product information on the bottle are printed in German only.

I have read rave reviews about this product on various forums and thought I would give it a try. It would be competing against what I usually use, Autoglym Vinyl and Rubber Care. I only intend to use this once a month on the door seals on my vehicle during the summer months and weekly during the winter. For its intended purpose it is very good. For application via the sponge on the bottle, I find AG V&RC a lot easier to apply via microfibre cloth to the rear or underneath of the seals. Same goes for the rubber plugs on the bottom of the doors and bonnet.

Winter for cars with frame-less windows is a right pain, windows might be clear after scraping the ice off but you still aren't getting in. I've been applying this once or twice a month over the winter months to the seals that meet the window edge and it hasn't failed to stop them freezing shut. The dealer wanted £40 to supply and use this on the seals when I brought it up at a service, but the mechanic told me to buy it on here, so for £8 you essentially get a years supply. The seals also look brand new with no fading or wear marks and I have never had a single water leak, a common problem for my car when the seals get old.

Product worked well for me. Revived several rather tired rubber seals on my car's folding roof. Before using it: several points on the seals would let in a bit of water during or after it rained heavily. Dripping onto various points in the cabin and allowing water into the boot. Some bits on the edge of some of the seals on the door were dried out, starting to allow mold to take hold and looking like they might start to crack. I've given it 3 or 4 applications and the dripping and leaks has reduced by at least 90%. the boot is now sorted and all but one of the leaks into the cabin are definitely fixed; I expect the final one to be resolved by one further application. The drying-out/cracking has been stopped. All looks a lot better as well as being a lot more watertight.

The instructions are in Polish so was unable to use the product without the unexpected effort of finding a translation. As my address is obviously in the UK, the company should have labels ready in the appropriate language.
