ℹ️ Note on black crowns

The black crowns have a blue protective coating. It disappears by itself over time and does not need to be removed. If you want to remove it beforehand, avoid polishing, as this can damage the black surface; thinner can be used carefully as an alternative. On the silver crowns, this layer, if present, can safely be polished off.
