The armoring of the chassis is carried out in two steps: first, cleaning, lifting the vehicle body with a hoist, cleaning the chassis with a cleaning agent, and washing away sand, oil and other debris to expose the metal surface. The second is to spray a layer of rubber elastic ive layer on the chassis. This kind of spraying can be performed multiple times or one time. Multiple spraying is relatively complicated but fast curing. One spray saves time but slow curing, the actual effect is the same. After spraying, you must wait until the surface is dry, that is, the surface is not sticky before you can drive the car away. Wait for the surface to dry for about 4 hours.Notes:1. There may be slight size deviations due to manual measurement, different measuring methods and tools.2.
