The whole idea behind paint sealant is to protect your vehicle's paintwork from the harsh environment that surrounds it - Ultra Violet rays from the sun which can fade paintwork, atmospheric fallout and acid rain which can damage the paint finish, road salt and other contributors which can fade and corrode the surface.
If the interior is left unprotected, the fibres of your car can soak up liquids and dirt, leading to unsightly stains and marks which can devalue your car. The invisible barrier applied by Supagard helps reduce friction between the fibres prolonging their life. This allows the Fabrics and Carpets to retain their natural texture and appearance.
