Sanding Techniques

Hold the sander with both hands for control. Your hands should be firm but relaxed. Avoid gripping too tightly. This can cause uneven sanding. Keep your arms steady and move the sander slowly. Smooth, even motions work best. Always keep the sander flat against the surface. This prevents gouging and damage. Practice on a scrap piece before starting on the car.

Apply light pressure when sanding. Let the sander do the work. Too much pressure can damage the car’s surface. Adjust the speed to match the task. Lower speeds are good for delicate areas. Higher speeds work for removing old paint. Always start with a lower speed. Increase speed gradually as needed. Check your progress often. Stop sanding if you see any damage. Use even pressure for a smooth finish.

Troubleshooting Common Sanding Issues

Do not stay in one spot for too long. Clean the sandpaper regularly. Dust and debris can cause swirl marks. Make sure to wipe the surface before sanding again.

Paint chipping can be frustrating. Check the paint condition before starting. Use a soft pad for delicate areas. Apply gentle pressure to avoid chipping. If chipping occurs, stop sanding immediately. Inspect the area for damage. Touch up with matching paint if needed. Always use quality sandpaper to reduce the risk of chipping.

Post-sanding Steps

Cleaning After Sanding

Clean the car thoroughly after sanding. Use a damp cloth to wipe away dust. Dust can affect the paint job. Vacuum the area if needed. Make sure no dust remains on the surface. Use a tack cloth for a final wipe. This ensures the surface is completely clean. A clean surface makes painting easier and results in a better finish.

Protecting The Sanded Surface
