Nano paintwork was developed using innovative nano technology and is a special coating that protects against dirt and dust. This type of paintwork considerably enhances the surface's soil-resisting characteristics so that it can repel water and dirt without any chemical assistance. The result: oily liquids, dirt and brake shoe residue hardly ever stick to the wheel's surface and if they do, they can be wiped away incredibly easily. Nano paintwork is also scratch and heat resistant as well as incredibly tough.
