It creates a compatible layer between the prepared metal and the rust treatment or topcoat, improving adhesion and helping to seal the surface. Brush-on primer works well for small areas, edges, weld seams, and spots where you need to work the product into pits and corners. Spray primer covers broader, flatter areas faster and leaves a more uniform film.
