Nano Sealant is a nano based spray sealant which offers a gloss boost and leaves an extremely hydrophobic coating to all exterior surfaces. Simply spray liberally on to wet panels and pressure wash off for an instant, very hydrophobic finish which lasts for 3-4 months. This product is also perfect for topping up existing protection that is on the car. Nano sealant will happily sit on top of ceramic coatings, waxes and sealants.
