Excelente producto! Lo adquirí ya que las gomas de las puertas de un coche con apenas dos años de uso comenzaron a hacer muchos ruidos con el movimiento del auto. Esto debido a que se encontraban resecas como resultado de la exposición a lluvias, polvo y un poco de sol. Una vez aplicado el producto en todas las gomas de las puertas los sonidos desparecieron por completo. Tenia mis dudas sobre los resultados de aplicar el producto, pero mis expectativas fueron superadas por completo. La textura del producto una vez aplicado muestra instantáneamente el resultado. Es un acabado no grasoso, por lo que no se pega más polvo del deseado. Es una compra que realizaré nuevamente para el detallado del auto.

最高に良いんだけど 購入追加したらus amazonにキャンセルされた🤪

Used it once so far and it seems to do what it says

This is one of the better products I've ever purchased. I originally bought this to recondition the seal around the moonroof of a vehicle that is parked on the street and exposed to Southern California sun and salty coastal air year-round, and has been for 16 years now. I was quite pleased with the result... and a bit surprised. I wasn't expecting the product to affect the moonroof's operation, but there's no more sticking or "pop" when it opens. So I started using the product in other places, too, like the rubber strip along the windshield cowl and the door & rear hatch seals. All show marked improvement, i.e. restored color and more flexibility. The only thing I don't like about this product is the applicator. For me, it takes quite an effort to get the flow of liquid going. Once the flow starts, it pretty much stays constant afterward; but once you tip the bottle right-side-up, you have to go through the process again. The foam pad on the applicator also turns black as you're applying the product, which can't be great for for it (but does show that the product is working, removing accumulated contaminants). Those are minor inconveniences, though, and not indicative of the product quality and effectiveness, both of which receive high marks. The bottle seemed small when it first arrived, but I only ended up using about half of it on the entire vehicle (a midsize SUV). I won't hesitate to buy this product again.

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!
