From available:
HAMMERITE or domestic Poly-R.

Good mangal.

Answer 5

There is such a thing as " hammer enamel ", they are different, there are those that can be painted on non-primed and not very prepared surfaces. The layer is not very thin, visually it also looks quite peculiar, but it keeps perfectly and fuss is at least.

Powder, as far as I know, is the most durable, but it also has a very complicated process - baking in an oven at a certain temperature, a certain amount of time. But in general, nothing is better for cases.
