High quality acrylic filling and sealing primer for partial and full automotive refinishes. Suitable for original or old paint work and ideal for unsanded OEM (E-COAT) panels. Its versatility enables both application at normal, medium and high film thickness with intermediate sanding or “wet on wet” application with an isocyanate based H729 Hardener. Dues to its high filling power and vertical stability, higher film thickness is possible. The fast drying and excellent leveling of this primer guarantee efficient application and fast sanding. It is cured with an isocyanate based H725 Hardener. Ready for sanding after 2-3 hours air dry at 23ºC (73ºF).
