Seems to work!
Used to condition and treat roof rubbers for a vw Eos. Before treatment one area of the roof was just pouring water in during torrential rain in December. 303 was applied by dabbing and spreading over all roof rubbers for a few days. This seemed to have helped during sibsequent bad down pours. Fingers crossed for the rest of the winter!

Really softened my rubber seals
I used this product yesterday, as I had washed and cleaned my car the previous day. Left it to dry thoroughly, and applied this product yesterday, my seals don’t feel brittle and dried out anymore. I am even doing the rubber seals on my double glazed windows.

Fantastic product
Amazing product, great results can be used on all rubber. My only negative is that the picture shows more then one of these giving the impression that it's a mulit pack.

Impressive
The seals around the convertible roof on my Merc had began to harden up and drip, after reading many reviews, I settled on this product and it's done the trick. Simple to apply, and I have done 5 so far but the rubber has become more flexible and is creating a water-tight seal, need to remember to apply it several times and the seal needs to be clean. It can drip a little so be careful, but it's sorted the seals and beats replacing the seals at £400 plus. Recommended

I’ve been using 303 Rubber Seal Protectant as part of my car detailing work, and it has become one of those essential maintenance products I rely on. What stands out about this protectant is how well it rejuvenates and protects rubber seals on doors, windows, hood, and trunk. I applied it to my 10-year-old car as a test subject, and the difference is remarkable — the seals look very good, feeling supple and flexible again, not stiff or brittle like untreated seals often do. For older or weather-worn seals, I noticed the original color and pliability return, which really helps maintain a tight, weatherproof seal around the doors and windows. The application is very user-friendly. The built-in foam-tip applicator makes it easy to target seals precisely without wasting product or making a mess. During application, it’s normal to see small white drops of the product on the seals, but once it dries, it leaves a smooth, clean, and well-conditioned finish. I simply wipe any excess after a few minutes — quick and straightforward. As a professional detailer, I can say this is a nice finishing touch that clients always notice. It elevates the overall look of the vehicle and adds that extra sense of care and polish that people appreciate. I find it especially valuable in hotter climates or when the car sits outside often. The product’s UV protection helps prevent the seals from drying, cracking, or fading due to sun exposure, which can save from costly seal replacements down the road. After treating my car, and a few customer cars at the shop, the difference is noticeable: doors close smoother, seals feel healthier, and there’s a lower chance of leaks or wind noise. Because of that, I consider 303 Rubber Seal Protectant a must-have for anyone serious about car maintenance or detailing. In short, 303 Rubber Seal Protectant works exactly as advertised: it conditions, protects, and revitalizes rubber seals. It’s inexpensive, easy to use, and gives a real improvement in seal performance and longevity. I’ll definitely keep using it and recommend it to others who want to preserve their vehicle’s seals.
