3. Clean, degrease and dry the surface according to the primer maker’s instructions.
4. Choose a compatible metal primer and finish system, and apply within the specified overcoat window.

• Painting over damp rust or loose flakes.
• Using an incompatible primer-and-topcoat combination.
• Grinding old unknown coatings without checking dust and exposure hazards.
