I tried this as a cheaper alternative to a German competitor product I’d used in the past. I think the competitor is worth the money. The 303 product is easy to apply, but I don’t see or feel a significant difference in the seals. Maybe it’s doing more than it appears, but the competition gave obvious and immediate results. The 303 product is water based and quite thin. I used the competitor product to coat an exposed sunroof seal, and after a heavy applications, the seal was noticeably more flexible and supple and soaked up the conditioner. The fit to the glass clearly improved and wind noise dropped. I don’t think the 303 product would rival that outcome with two dozen applications. It’s a light rubber dressing in my opinion, but not a serious conditioner or restoration product. I’ll go back to the competitor.
This product was designed to protect your car's rubber seals from drying out. Protecting these seals is very important because they are not easy to replace on some vehicles. The manufacturer may also stop making replacement seals if the vehicle is an older model. Replacement parts become harder to find on non-popular makes and models. It is in your best interest to take care of these often neglected parts. Spend more effort taking care of rubber door and window seals than you do on your tires. Tires are easily replaced. These seals are not.
This rubber seal conditioner and protector from the 303 brand claims to prolong the life of these parts. I will be honest in this review and say that the only true test of how well this product works is the test of time. Keep applying this product according to the frequency in the instructions. Clean your rubber seals gently. Do not expose them to harsh cleaners. That is all you can really do.
The foam applicator at the tip of the bottle allows you to apply the product without making a mess. However, if you are doing the rubber seals on an SUV or some other large vehicle, the foam will not last. You may have to open the bottle and apply the remaining chemical using a microfiber towel. This product would have earned a 5 star rating if the foam applicator had been more durable. But that is not a deal breaker because you can always apply using a microfiber towel.
The product applies easily and smoothly. The liquid disappears immediately. I suspect the rubber seals absorbed the liquid. Be careful if your rubber seals are cracked. Further rubbing could make them deteriorate and fall apart. No product can save rubber seals that are already broken down. You will first need to clean the seals with a soft-bristled brush if they are dirty. Wait until it dries and then apply the 303 protector. Clean the mating surface. Whatever body panel makes contact with the seals, usually another rubber seal, should also be cleaned.
Highly recommended. At this point, I will have to accept the manufacturer's claims for the product. The 303 brand is a big company and I would assume they have the resources to create a formula that protects rubber seals. They make other car care products that usually get good reviews from consumers. I expect they have enough chemistry people on their staff to create these products.
This is a water based product. It syas it on the side. I noticed that after seeing the product bead up on the door and window weather stripping on my mazda CX5. Folks, the vast majority of rubber used in automobiles is chemically resistant rubber. A water based "solution" is nothing more than a placebo. It was immediately apparent that this product was not conditioning my rubber. I noticed significantly better results using Meguirs vinyl protector. Find a solution that will restore the rubbers lost oils and offer protection from UV damage. This is not it.
This is the best stuff I've found for the window trim on our vehicles. My truck was a bit neglected, so the first application soaked in pretty quick. The second coat though, has lasted a good long time. I'd say it's been almost two months and the trim still looks good. It's probably time for another application, but it's still 100% better than before. The application is really easy with the sponge applicator. This is good stuff, I'd definitely recommend it.
Seems to work. I used it on the weatherstripping around my car doors and it seems to lower the wind noise. One caveat - clean your weatherstripping with soap and water before you apply this. A good cleaning, especially at the bottom of the doors, will give you the best results. Apply this a couple of times per door and cover every inch of the weatherstripping. Even the hard to reach places.
