The difference between monocoque body and body-on-frame structure: 1. Different advantages: The monocoque body is lightweight, low in height, and easy to assemble; the body-on-frame structure has an independent frame, higher chassis strength, better anti-jolting performance, and better stability and safety. 2. Different disadvantages: The monocoque body has weaker torsional rigidity and load-bearing capacity; the body-on-frame structure is heavy, costly, has a high center of gravity, and poor handling. 3. Different frames: The monocoque body does not have a rigid frame, only reinforcing parts such as the front, side panels, rear, and floor; the body-on-frame structure has a rigid frame, with components such as the engine, part of the transmission system, and the body mounted on the frame via suspension devices.

What is the function of car wax?

Car wax serves the following functions: 1. Waterproofing; 2. High-temperature resistance; 3. UV protection; 4. Anti-static; 5. Gloss enhancement; 6. Polishing and buffing; 7. Protection against acid rain and salt spray, among others. The choice can be made flexibly according to needs. Car wax is a traditional automotive paint maintenance product, primarily composed of natural or synthetic wax. It penetrates into the gaps of the paint surface to smooth it out, thereby enhancing glossiness. Being an oily substance, car wax has poor adhesion to the paint surface and offers short-term protection. This type of wax often washes away due to rain or rinsing, sometimes even adhering to the windshield and forming greasy stains. Therefore, regular automotive waxing is required.
