I have been using it for over a year now, it solved the problem of restoring the appearance on the winter plastic mats of my car for one reason only: it makes the plastic look new WITHOUT being slippery, which is important for safe driving. It also does not leave a shine but the factory appearance and touch of the plastic when it dries (quite quickly, in less than a minute). It does not contain silicone and a few drops are enough in an applicator to cover the entire mat. With one bottle, you can go for years and not just months, even though it needs to be applied frequently and after washing the mats to always have the same result. I also use it on the interior plastics. If you want protection as well as restoration, then it is not for you, but for the mats I don't think you can find anything better, always in my amateur opinion.
