nextzett Gummi Pflege Rubber Care Stick – Car Weatherstrip & Seal Conditioner – Prevents Freezing, Cracking, Fading – 3.4 fl oz

I've been using this when detailing cars and have been very happy with the results. The applicator is easy to use, the product does a good job moisturizing without feeling greasy, and lasts a long time. Used on quite a few BMW, Tesla, and Porsche, so far so good. Their customer service line is also super friendly and helpful. I've used a few other products that come in spray bottles, and even though they offer more product for the money, I'd recommend this because a little goes a long way, and lasts quite a while. You can easily go 6+ mos. between applications.

Works great but shipping could be better. Cap came off and also the foam applicator, probably lost half of the stuff but I didn't want to deal with a return so I'm still using it. Pretty annoyed, all they need to do is add tape to cap, instead they throw it in a loose plastic bag and wish it luck. Thanks Amazon.

Product works well. A little goes a long well. If you run your car through the car wash by the second wash you will have to reapply. Over all it helps the rubber trim around my windows from looking dry.

This is made for RUBBER SEALS. Like the weatherstrip around your doors, trunk, etc. Almost all the reviews here show people applying it to the wrong parts, like bumpers and door handles. That's NOT what it is for. And all the bad reviews are due to poor shipping, so ignore every single one of those. This stuff works great, and the applicator works great if you bother to READ THE INSTRUCTIONS. I have a couple vehicles that have top covers and will squeak, especially off-road. Applying this to the seals makes them soft like silk, and the squeaking is gone. Has a light citrus scent which I don't particularly like, but it's not offensive and after a day the scent is completely gone. I tried this on one of my older cars, and it stopped the squeaky weatherstripping on that one too. Good stuff.

GummyPflege has become my go-to solution for rejuvenating the rubber seals on my personal vehicle, and the results have been nothing short of impressive. It's not just a cosmetic fix; it's a preventative measure that adds a layer of UV resistance, enhancing the longevity of my car's rubber components. What struck me immediately was the versatility of GummyPfledge. The applicator made it easy to target specific areas like the exterior window trim, convertible top seals, and windshield wipers. The gel-like watery consistency ensured a mess-free application, even on vertical surfaces (some drips are possible if you squeeze the bottle and expel too much of the product). The transformation was visible right away, bringing back the deep, rich color to faded rubber. The application process was a breeze, and I appreciated the quick results. However, what sets GummyPflege apart for me is its added UV resistance. Living in an area with intense sunlight, this product serves as a vital preventative measure against the damaging effects of UV rays. I had to replace rubber windshield trim due to uv damage and I applied a layer of this immediately to the new seal. It's reassuring to know that my rubber seals are not only looking revitalized but also shielded from environmental elements.

Maybe it doesn't have the exotic unicorn extract, but this stuff is impressive! I love it! Be sure to clean the door seals thoroughly. Grab some all purpose cleaner and a tooth brush if you have to, and really get the seals clean - it will extend the life, and effectiveness of the product significantly. It smells like citronella, - like those mosquito candles you buy during the summer. On solid (dense) rubber it kind of just beads up, but as it dries if you continue to "buff" this into the rubber, it goes on even and then dries completely. On porous rubber, like most door seals from the 90's and 2000's, It starts soaking in immediately (if DRY) and gives a dull, matte sheen at first. The more you massage this in, the more apparent it's effects start to be, and the glossier it becomes. You don't want to go crazy though. After drying, I went over and gave one more application to the obviously worn spots on the seals, just for good measure. The following day, the seals look like brand new. I didn't notice any swelling of the rubber, but the texture is softer and I can tell just by feeling them that they will seal better. They seem more plush and pliable, flexible, and durable. As a detailer, I generally spend a good amount of time cleaning door jambs properly - no magic spray-and-hide tactics here. Often times on older vehicles the rubber has began to deteriorate, and will eventually stick to the paint inside the jambs. This seems like it can reduce and/or eliminate that problem if you use it early enough in the vehicles life and keep them maintained. At $8-9, this is affordable to keep on hand. In a nutshell, I am going to be buying another couple of these to have on hand as it's a great finishing touch to a detail! My ONLY dislike about this product, is that it's applicator is kind of lack-luster. The foam is not very dense, super soft, and doesn't hold a lot of product. I found that the foam immediately discolored (turned black) and it was not applying much product to the seal. You have to think shoe-polish, because that's exactly what this bottle is like. Has a pressure-valve at the end that releases product when you push on it, but the bottle has to be upside down for that to work. I think if you had small foam applicators, or even of those dense foam brushes from a hardware store, you could make a smaller, makeshift brush to apply to the seals inside a door jamb - this bottle doesn't allow that on some vehicles. I wasn't worried about getting any on my hands, so I went to town - but at some point the foam WILL fail and you'll be forced to use another application method. YMMV. 5 stars because this product rocks, and I wish I knew about it sooner. It is now part of almost every detail job I do.

Good product, it does keep my doors from freezing up and sticking. Use every winter.

My car is 23 years old, added this to the seals around the top and the doors and windows, no more noise. Works great
