Method of automobile chassis armor: 1. Park the vehicle on the car lift at the construction site and fix the support points. After the vehicle rises, clean the chassis, especially some corners, and pay attention to the dirt on the wheel arc, fender and fender liner; 2. After the chassis is cleaned, it is necessary to prepare for chassis armor, and cover the hub of the car to avoid painting on the hub when the chassis is armored; 3. Check whether the air pressure of the sprayer is enough. If it can't be used enough, you can spray the fender of the vehicle first, and shake the container fully before use to avoid the phenomenon of poor effect. After spraying for about 20 to 30 minutes, touch the chassis armor with your hands. When the armor surface is dry, the car can go on the road. The scientific name of automobile chassis armor is automobile chassis anti-collision, rust prevention and sound insulation. It is a high-tech adhesive rubber asphalt coating, which is non-toxic, high coverage and high adhesion, and can be sprayed on exposed parts such as automobile chassis, wheel hub, fuel tank and automobile lower panel.
