The Mipa CX4 kit with HS hardener is an innovative high solid express clearcoat for extremely fast force drying. Using HS hardeners will slow down the drying time and widen the polishing window. This makes it ideal for busy bodyshops that need a high quality clearcoat that has fast drying properties but isn't smart repair fast. Especially suited for spot repairs or partial resprays. Easy and safe application with results of highest quality. If using for smart repairs, we recommend the HX4 hardener. Kit contains: 5L clearcoat & 2.5L hardener.
