I've been using the 303 Rubber Seal Protectant on my 15-year-old SUV, and the difference is night and day. My door seals were starting to look faded and felt stiff, but after applying this, they’re soft, supple, and even regained some of their original black color. It’s like giving your car a mini spa treatment!

The foam applicator makes it super easy to apply—just dab and spread. No messy drips or greasy residue. I especially love how it absorbs quickly, so I don’t have to worry about smudges or attracting dirt. Perfect for quick touch-ups before a road trip.

Living in a sunny area, UV protection was a big selling point for me. After a few months, my seals still look great, with no signs of cracking or drying out. It’s also worked wonders on my sunroof seal—no more annoying squeaks when it’s hot outside.

Pro tip: If you’re working on larger seals (like those on an SUV), the foam applicator might wear out fast. I switched to a microfiber towel halfway through, and it worked just as well. Not a dealbreaker since the product itself delivers.

For the price, this little bottle packs a punch. Whether you’re reviving an old classic or maintaining a daily driver, this is a must-have for keeping rubber seals in top shape. Just remember: it won’t fix already cracked seals, but it’ll definitely prolong the life of healthy ones.
