I originally bought this to recondition the seal around the moonroof of a vehicle that is parked on the street and exposed to Southern California sun and salty coastal air year-round, and has been for 16 years now. I was quite pleased with the result... and a bit surprised. I wasn't expecting the product to affect the moonroof's operation, but there's no more sticking or "pop" when it opens. So I started using the product in other places, too, like the rubber strip along the windshield cowl and the door & rear hatch seals. All show marked improvement, i.e. restored color and more flexibility. The only thing I don't like about this product is the applicator. For me, it takes quite an effort to get the flow of liquid going. Once the flow starts, it pretty much stays constant afterward; but once you tip the bottle right-side-up, you have to go through the process again. The foam pad on the applicator also turns black as you're applying the product, which can't be great for for it (but does show that the product is working, removing accumulated contaminants). Those are minor inconveniences, though, and not indicative of the product quality and effectiveness, both of which receive high marks. The bottle seemed small when it first arrived, but I only ended up using about half of it on the entire vehicle (a midsize SUV). I won't hesitate to buy this product again. Review: Great product. Works as intended. I use it on all my cars, old and new. - I love this product. I use it on my older car and also on my new car. Great for keeping those rubber seals flexible and working and looking like new. Keeping those seals around doors, trunk, and hood flexible as new is crucial to maintain a quiet ride and to avoid water intrusion issues with your cars. Recommended. ## Features - REVITALIZE AND RESTORE RUBBER SEALS: 303 Rubber Seal Protectant penetrates deeply to rejuvenate and restore the color and flexibility of aging rubber seals, ensuring a "like-new" appearance and performance. - VERSATILE APPLICATION ON MULTIPLE SURFACES: Perfect for use on all rubber, vinyl, and plastic surfaces, this protectant not only enhances the shine of your vehicle's seals but also works wonders on interior and exterior trim for comprehensive care. - DEFEND AGAINST UV DAMAGE AND CRACKING: Our advanced formula provides powerful UV protection, shielding rubber seals and trim from harmful sun exposure to prevent fading, discoloration, and cracking over time. - NON-GREASY FINISH FOR CLEAN SURFACES: Unlike traditional dressings, 303 Rubber Seal Protectant dries to a smooth, non-greasy finish, ensuring surfaces feel clean and avoiding the attraction of dirt and dust. - USER-FRIENDLY APPLICATION: Designed for convenience, just simply wipe the applicator on any rubber surface or seal to achieve professional results effortlessly. - PROVEN TO PROTECT: Backed by over 40 years of field-tested reliability, 303 Products safeguards your cars, boats, and outdoor furniture from natures harshest conditions.

Back when I used to watch Scotty Kilmer (before he got super whiney & political), he showed that AT-205 & water will "recondition rubber" like it does when used in a trans/engine/power steering system/diff. I use Dielectric Grease (pure silicone grease) to keep the rubber on my car nice & supple. I apply it with my hand, let it sit & soak in for a few minutes, massage it in a little, then wipe it down. It works beautifully, and keeps the rubber (tires are treated differently) looking/feeling/performing as good as or better than new. **Q: Can this be used on sunroof seals?** A: I do not see why it can not be used on sunroof seals. I just purchased the rubber seal protectant but I have used other 303 products and love them. **Q: Is this product better or worse than einzette gummi pflege? thanks!** A: Hello,Einzette gp is generally used for interior rubber, as it is water-based and will get runny when wet. It is still very effective on exterior rubber-like components if buffed dry tokeep excess liquid at a minimum. Einzette can be used if you are willing to work just a bit to buff out your exterior rubber to a nicw shine; it is not a spray-and-forget type ofrubber protectant.I sure hope this helps. **Q: Can the applicator be refilled once all 303 protectant is used? Or is this a sealed cap that once it's empty you have to buy a new one at $9.98.** A: where to buy 303 protectant at $9.98 Norm - ## Customer Reviews ### ⭐⭐⭐⭐⭐ 303 Rubber Seal Protectant *by J***W on June 23, 2026* This is one of the better products I've ever purchased.
