303 Products Rubber Seal Protectant – Protects & Conditions Seals on Doors, Windows, Hoods, Trunks | Rejuvenates Color & Flexibility of Old & Dry Seals | Weatherproofing & UV Protection, 3.4 fl.oz

I bought a 24 year old convertible and used this product on all the rubber seals associated with the soft top, door seals and engine seals. I don't know how long the product will extend the life, but they look really good now and feel soft to the touch and not brittle at all. Seems to work well.

Arrived quickly, tried it, seems to work very well

Protects the rubber seals on your car.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.

Listen, my car window was squeaking like it was auditioning for a horror movie soundboard—every roll up or down was a nails-on-chalkboard nightmare. Neighbors were starting to think I was running a haunted house on wheels. Enter Squeak-Be-Gone Window Lube! One quick spritz of this magical potion, and my windows are gliding smoother than a figure skater on fresh ice. Silent as a ninja, swift as my dreams of escaping awkward small talk. My car is now the strong, silent type, and I’m pretty sure it’s thanking me with every quiet roll. 10/10, would lube again! 🚗💨
