Grey Primer is widely used for protecting the metal items against corrosion and to extend the life before repainting becomes again necessary. This primer is often used in the car bodywork garages to spray the surfaces of car or vehicle body panels. This primer is a paint product that allows finishing paint to adhere much better than if it were used alone. Grey Primer has several benefits, such as better touch-up, superior hide and more uniform colour. This primer also acts as an undercoat which is applied on materials before painting. This primer ensures better adhesion of paint to the surface, as well as increases paint durability. This primer is very cost effective and easy to apply on different metallic items.
