Satisfactory for its price. If you have your own house, change the bathtub. Ideal and cheap for rental houses where the owner is not likely to easily go through such a process. It does not have the texture of a classic bathtub, but as you can see in the photos, this carpet that was created by a previous tenant of the apartment disappeared. Depending on how much enamel has come off, it requires more hands. I used 4 hands with 2 of the 400ml, but the enamel had come off everywhere. Also, like with all spray paints, you need to know how to work with it because it will run everywhere. Due to my own stupidity, it made 2 runs that are not visible, of course. When holding it, I feel like it will last for a long time. We will see.
UPDATE after 3 years! The coating has come off where the enamel was lost. I easily did it again with such a cheap solution. I think I still have some spray left.
