Paint correction is the process of removing surface imperfections from a vehicle's paint, such as swirl marks, scratches, and oxidation. It involves using specialized tools and products to level out the paint and restore its clarity and shine.

The length of time it takes to complete a paint correction job depends on the severity of the paint defects and the size of the vehicle. It can range from a few hours to several days.

Paint correction can remove some deep scratches, but not all. If a scratch has penetrated through the clear coat and into the base coat, it may not be possible to remove it completely without repainting the affected area.

When done correctly, paint correction should not damage your paint. However, it does involve using abrasive compounds to remove imperfections, so it should only be performed by a skilled professional who understands the proper techniques and products to use.
