Bulls Eye® 1-2-3 is a universal interior and exterior, water-based, primer-sealer. It offers low odour application, quick drying convenience and excellent adhesion to glossy surfaces. It effectively primes and seals a wide variety of interior and exterior surfaces. A 'bond coat' primer that’s great for hard-to-stick surfaces, it offers excellent adhesion without sanding. Bulls Eye® 1-2-3 also prevents rust formation when applied over clean ferrous metal such as iron and steel. Bulls Eye® 1-2-3 contains a biocide that protects the dried coating against fungal degradation, making it ideal for high-humidity areas such as bathrooms and laundry rooms. Bulls Eye® 1-2-3 is great for blocking stains. It permanently and completely seals graffiti, grease spots, tar and asphalt - inside and out Bulls Eye® 1-2-3 is rust inhibitive and ideal for new metal. It resists flash rusting in its "wet" state - and provides rust resistance for the life of the coating.
