|Product is recommended as a primer coat onto steel. The rust should be wire brushed and excessive powder removed before priming with the etch primer. Can be spray applied or brush applied and thinned to the desired viscosity with a special etch primer thinner. Dries extremely quick to a matt/ suede finish. Product is more a surface treatment than a paint and must be overcoated. Neutralises and prevents rust formation. Contains an acid that etches into the metal giving excellent adhesion. Heat resistant up to 200 °C.
