To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
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.
I took a gamble and thought I'd try this instead of the spray bottles, to save the use of a microfiber. It does work well, but the sponge gets dirty, so you sort of spread the gunk around all your trim during application. Would echo others and say just to get the spray bottle of 303.
This seems like a decent product to use to protect automotive rubber weather stripping, but I think it is priced a little too high. The applicator bottle is acceptable, and will help minimize waste. The finish seems to hold up for a couple of Months, but does not seem very long lasting. I will continue to research like products and may try one or two others to see how they compare. Yes, it does work, but I question the price and durability of the finish. Would like to find something that seems to last longer.
I bought this to see if it would help the door and trunk gaskets seal on the hard top convertible on my MB SL550, which has a couple leaks at the car wash. When I first applied it per the directions, it didn't seem to help. But after a few days, the door and trunk seals no longer leaked. It isn't long lasting, though. It really needs to be reapplied about every 3-4 months.
Relatively inexpensive alternative to the $95 item recommended by Mercedes-Benz. Originally purchased to lubricate the air intake gasket between the air cleaner and the air intake manifold. I am using it to address the dried out rubber seals on the exterior of the automobile. I don't know if it will help with deteriorated seals, but it should be useful in protecting newer rubber seals.
This makes it easier to hit the trim and weather seals of your car. You can’t squeeze too hard or the top might pop off. The thing I don’t like the most is that the cap does not seal shut, therefore it’s allowed to breath and if you place this anywhere above room temperature you can actually see the product appearing to evaporate inside the cap.
