Review: Excellent rubber door gasket rejuvenator - I bought this in an effort to save an aging door gasket on a classic car...needless to say, getting a proper new door gasket was going to be a challenge and the "one size fits all" means "one size fits none". The product worked extremely well and the gasket is now sealing properly, without having to be replaced, definitely a win in my book. It may not solve all problems, but for just a few dollars it is worth trying before replacing an entire door gasket.
Review: ONly thing which takes away the sticky surfae of old rubber or plastic - Sticky rubber or plastic surface? This is the only thing I have found that actually works to fix that. So you know the horror of discovering something you have had for a while is de polymerizing and either becoming brittle or sticky. The brittle is bad enough but the sticky is worse as you cant use it without being reminded of what it shold feel like. So I have tried all the normal advice- soap and water (hah!), wife's makeup remover, olive oil, different alcohols (methyl, ethyl, iso propyl), Acetone, Armor All, Goof off glue remover, Goof off regular, nothing helped. In fact the regular goof off and acetone started to take off the rubber coating and made things substantially worse. I reluctantly asked ChatGPT thinking it would have no clue but it gave me some suggestions including this stuff. Its like old fashioned shoe polish- liquid in a bottle with a foam applicator on top. I tried it once and it was better. Not great but better. I let it dry and ran two more coats on it (Sweet Dell Xeon laptop from 2015) and to my amazement it solved the sticky problem and other than being glossier, its almost identical to my current Dell laptop. I beleive its a silicone based solution so it should not wash off as I need to occasionally wipe down the keyboard. I now have a whole range of stuff like tools and things that are next in line to get coated. It doesnt undo the damaged plastic or rubber due to oxidation over time and loss of polymerizers but makes the surface at least usable again. I have some automotive targets in mind as well. Fairly inexpensive solution to a vexing problem. No I didnt get it for free, I always pay full price usually after trying everything else that doesnt work but thats life.

## Questions & Answers

**Q: Is this just a small bottle/applicator of 303 Aerospace Protectant?**
A: I'm willing to bet it's just AT-205 Re-seal, watered down. 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

*by J***D on September 14, 2025*

Sticky rubber or plastic surface? This is the only thing I have found that actually works to fix that. So you know the horror of discovering something you have had for a while is de polymerizing and either becoming brittle or sticky. The brittle is bad enough but the sticky is worse as you cant use it without being reminded of what it shold feel like.

### ⭐⭐⭐⭐ Protect your car's rubber seals.
*by C***I on July 29, 2018*

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.
