Can the gourd be colored after polishing?

Gourd can be colored after polishing, which is naturally old after a long time, but the disk surface is not excellent and cannot be magnetized.

Sunbathing and air-drying gourds can be pre-polished with coarse-grained towels, and sunscreen treatment can be carried out at the same time. Because the gourd was completely dried, it could not be used directly before. Pre-polishing should start with smooth, round and delicate gourd skin, and be properly exposed to the sun. After the preliminary work is completed, continue polishing with a fine-grained towel, preferably with a porcelain hanger, and then you can play with your hands.
