Step 15: Dry and polish

Put the car in the oven at a temperature of 60-80 degrees Celsius for about 30-45 minutes to help the paint layer dry faster and harder. After drying, use fine sandpaper and a polishing machine to grind the paint layer, creating a beautiful shine and removing paint particles and small scratches on the surface.

Step 16: Wash car and check

Finally, wash the entire car and dry it with a soft towel. Re-check paint quality, color, and gloss. If it meets the requirements, the vehicle will be handed over to the customer.
