How can scratches in an enameled bathtub be concealed?

We also had to do that once because the dog often went crazy when bathing. He doesn’t like water, and bathing was always terrible for him. Since we didn’t know any better, we had a special company come. They used this kind of substance. From that point on, the dog was bathed in a [Kinderbadewanne], and we had no more problems, and it lasted forever.

I also bought a set like that from the hardware store. But it is really hard work and not meant for rough hands. But after a few attempts, I managed to do it. I just hope it lasts for a while.

But that is hard work and not meant for rough hands.

and I always thought hard work also requires rough hands, hmm how wrong one can be :p
Regarding the repair kits, I find this one a good solution, if the tub is too scratched then there are even new coatings available, but they are very expensive, so in some cases buying a new tub is worthwhile.

I know the problem too, but with my bathtub the scratches never completely disappeared. I used some kind of enamel from the tube. Somehow there is a color difference there.
