1.Check Color: Ensure the color and code on the touch-up pen cap match your target shade. 2.Test First: Test the paint on an inconspicuous area or scrap metal to confirm the color and finish meet expectations. 3."Connect the Dots" Technique: Use this method to apply paint, avoiding blobs and ensuring even coverage. 4.Less is More: Apply a small amount initially and build up gradually if needed. 5.Layering: If the first coat doesn't fully cover or blend, allow it to dry for 10-15 minutes before applying a second coat. 6.Dabbing Motion: Use a dabbing motion instead of brushing to avoid visible strokes and achieve a smoother finish. 7.Patience and Care: Double-check colors, test beforehand, and apply thoughtfully for the best results.
