It doesn't have that enamel look it used to have, it seems like it's painted, moreover various bits of dirt and dust don't come off easily like before, but stick and you have to push them and use water. All this even though I applied two coats of varnish. Of course, the bathtub became white and has a different look of cleanliness

Very nice coverage, I painted a green bathtub with three coats and it has lasted until now. However, it is sensitive to impacts, for example if the shower head or a generally heavier object falls on it. There is a high chance it will peel. However, I am very satisfied.
