Certainly - a factory impregnation of a new product is, of course, nothing. But after some time they can more or less quickly. After a few tries with other products, I came to a recommendation from the sports shop of my confidence about this product. At first I tried the spray Nikwax TX Direct Spray. That worked quite well, but did not last long, but was quick to make a trip before. After that I have ever tried this impregnation and was thrilled. Certainly, the impregnation does not last forever. Depending on the load and number of washes, the impregnation must be renewed. Value for money is also great (had paid for 300ml in the store 13,99).
