-
Remove Rust: Use a wire brush or sandpaper to eliminate rust spots.
-
Sand the Surface: Lightly sand the area to create a rough surface for better adhesion.
-
Apply a Primer: If necessary, use a metal primer to enhance adhesion and protect against rust.
-

Application Techniques for Spray Paint
Proper application techniques can greatly affect the quality and durability of your paint job. Here are some essential tips:
Shake the Can
Always shake the spray paint can vigorously before use to ensure even distribution of the paint and propellant.
Test Spray
Before applying to your main surface, do a test spray on scrap material to check the color and flow.
Maintain Distance
Hold the can 6-12 inches away from the surface to avoid drips and uneven coats.
Use Smooth Strokes
Apply the paint using smooth, sweeping strokes to achieve an even coating. Overlap each pass slightly.
Multiple Thin Coats
Instead of one thick coat, apply several thin coats, allowing each to dry before applying the next. This prevents runs and ensures a durable finish.
