The E-Tech Technik Filler & Primer is designed to fill in minor scuffs and surface imperfections up to 0.5mm while simultaneously priming the surface. This allows for the top coat of paint to go on shortly after drying. It is perfect for filled and sanded surfaces, ideal for smoothing out textured or rough surfaces, and its high build nature and easy sanding provide great surface leveling properties. It can be used on most painted or unpainted metal surfaces, rigid plastics, glass fibre, wood, and masonry.
