Bulldog Sealer & Adhesion Promoter is the only one-component sealer/adhesion promoter that can be used on both metal and plastic. It seals primed metal and plastic surfaces, offering quick dry times and excellent holdout while filling scratches. It dries clear so it can be used for jambs and edges, but can also be tinted with basecoat for better hide. Also, it’s compliant with 2010 national regulations for adhesion promoters.
