Application Instructions

• Preparation: Surfaces must be clean, dry, and free of oil, grease, and loose rust/paint. Lightly sand glossy surfaces.
• Shaking: Shake the can vigorously for at least one minute after the mixing ball begins to rattle and frequently during use.
• Spraying: Hold the can 10-12 inches from the surface. Apply primer in light, even, sweeping strokes. Avoid heavy coats to prevent drips and ensure fast drying.
• Sanding: Once dry, lightly sand the primer coat (e.g., 220-320 grit) to remove minor imperfections and ensure a smooth base for the topcoat.
• Clearing Nozzle: After use, invert the can and spray until only clear propellant is released.

Pro Tips

• For the best protection on metal, apply two thin coats of primer, sanding lightly between them.
• Always check the topcoat manufacturer’s instructions for primer compatibility.
• Using a grey primer is ideal beneath most final colors (especially blue, green, and silver). Use a white primer for bright yellow or orange.
• Work in a well-ventilated area, and wear a respirator mask suitable for solvent fumes.
• Do not apply the topcoat until the primer is fully dry and sanded smooth.
