China said crystal plating; It is called car paint sealant abroad.

Mixed sealant refers to sealing glaze and coating.
Chemical sealant is what we call crystal plating.
Crystal plating (domestic name) first came from Japan and was developed by Japanese scientists. Can have wear resistance, sealing protection, and prevent corrosion and oxidation.
Later it was bought by Germany and other countries. Now many countries have their own brands of plated crystals.
At present, many foreign electroplating brand electroplating shipment factories are still in Japan, all of which are purchased from Japan.
