What is Automotive Paint Spot Repair?

A spot repair consists of repairing small areas of a car’s paint. Unlike repainting the entire vehicle, a spot repair focuses on a single area of damage, resulting in time and money savings.

Defining Spot Repair vs. Full Repainting

Spot repair works best for:

  • Small scratches
  • Rock chips
  • Minor scrapes on your bumper or fender

Full repainting needs the entire car or large sections, which costs much more.

When to Consider Spot Repair

Spot repair costs less for minor damage. It keeps your vehicle’s factory paint intact without needing to respray large areas.

Common Causes of Paint Damage Requiring Spot Repair

Everyday Causes of Paint Damage

Your car’s paint faces many threats:

  • Road debris and rock chips
  • Parking lot and shopping cart dings
  • Sun damage, bird droppings, tree sap

Stopping Further Damage

Leaving scratches untreated leads to bigger problems:

  • Rust forms
  • Clear coat fails
  • Repairs cost more later
