Review: 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.
Review: Used it once so far and it seems to do what it says

## 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 B***T on 19 December 2024*

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!
