Coated with Sapphire serum materials with nano technology that formalized permanent coat against paint. This also has the hardness equivalent to sapphire glass (9H+ 5Mohs).
Ceramic Quartz from Topcoat is a coating product with the best super ceramic (9H+) material. The reason for that is the material is clear and thin yet hard, been through extreme bending test, 3x stronger compared to other nano ceramic.
