My tub had to be sealed to the sides of the tiles, because I did not know exactly which silicone has been used, I have this silver-gray actually first ordered a trial basis. The cartridge was well packed and the silicone fresh, so any old commodity. I have to say top. Adjusts color to the already processed silicone and is easy to process. Since I am not an expert and only home improvement, I do not know what great differences there are more expensive products in terms of processing. This silicone fulfilled its purpose in my eyes very well, is easy to apply, does not tear and a good seal.
For over two months, it is in my bathroom processors and I can see no color differences still leaks, so I would buy it again at any time and process.
