A nano ceramic coating is the best protection on the market today. The advanced technology in a ceramic coating will allow it to bond to a surface semi permanently, which means it protects your vehicle for years to come.
The properties of the coating also give it a self cleaning and hydrophobic effect making it want to repel anything that comes in contact with it, which in return means a better protected vehicle and easier maintenance.
The coatings lifespan when properly washed and maintained varies from coating to coating but it is as little as two years or as many as nine. Depending on the level of protection wanted.
