Wash the chassis after rain to reduce rusting
Under the high temperature baking in summer, the impact of gravel on country roads, and the silent attack of acid rain, the steel and iron chassis will be scarred, rusty and even "full of holes." Exhaust gas, dust, noise, and humidity will seep into the body through tiny holes in the chassis, causing the body to corrode and peel off.
"Chassis plastic sealing" is different from general rust prevention treatment. It sprays a highly adhesive flexible rubber resin on the chassis, isolating it from the outside world to achieve anti-corrosion, rust prevention, and sound insulation functions, extending the life of the body. Before "chassis plastic sealing," a special degreaser must be used to remove asphalt and oil stains attached to the chassis and then dry it. Any stain will affect the firmness of the plastic sealing. Before plastic sealing, the transmission system and exhaust system's heat dissipation parts need to be covered to avoid affecting the normal operation of these components after plastic sealing. Secondary plastic sealing can improve sound insulation and collision resistance effects, but there should be a 20-minute interval between the two sprayings, waiting for the first layer of plastic sealing to completely dry before construction. For older cars, since the cleaning work of the chassis is relatively large, it takes longer, about 3 hours.
Car beauty's chassis armor makes your car last longer
Most car owners, especially new car owners, care a lot about their cars. Even if there are slight damages on the car's paint surface, it will cause the owner great pain. But have you paid attention to the condition of your car's chassis? When your car undergoes routine maintenance or tire replacement at an auto repair shop or tire store, take a look at your car's chassis under the lift: you will definitely be shocked. The chassis is full of scars and rust spots, almost unbearable!
If rust prevention is not done properly, it will greatly shorten the lifespan of your car. Because the car chassis cannot remain clean; once driven, a large amount of mud and dirt will adhere to it. Mud contains a lot of moisture, which erodes the metal surface over time, causing rust to penetrate deep into the metal, eventually leading to sheet metal perforation, or even the frame rusting through, with very dangerous consequences. Therefore, it is necessary to give the chassis a comprehensive and thorough armor and plastic sealing before rusting occurs. Chassis armor involves spraying 3-5 layers of special rust-proof glue on the car chassis, like adding armor to the steel plate of the car chassis. Its function is primarily rust prevention, followed by increasing the elasticity and wear resistance of the chassis, and thirdly reducing noise.
The six steps of car beauty's chassis armor
Step 1: First raise the car, use a high-pressure water gun to rinse the chassis, apply engine external cleaner or engine degreaser, remove the oil mud and sand adhered to the chassis, or use special sandpaper to grind off the original rust-proof layer;
Step 2: Use a blow gun to blow out the water from the gaps, and use a towel to dry the water.
Protect the car's chassis by plastic sealing
Most driver friends pay great attention to the maintenance of the car's mechanical parts and body, but often neglect the protection of the car's chassis.
After it rains in summer, the car chassis will splash with thick mud. If not cleaned in time or not thoroughly cleaned, it will cause great corrosion to the chassis, shortening the car's lifespan. Therefore, it is recommended to perform a "chassis plastic sealing" care for the car chassis, providing lifelong protection for the chassis. Car paint maintenance
Car "chassis plastic sealing" is to spray a thick layer of highly adhesive, highly elastic, highly anti-corrosive and moisture-proof flexible rubber resin on the chassis, isolating it from the outside world to achieve anti-corrosion, rust prevention, and anti-collision functions. It also blocks some noise from the bottom.
Before "chassis plastic sealing," the mud, oil stains, and rust spots attached to the car chassis must be thoroughly removed. After a detailed cleaning and drying process, cover the rotating parts such as the drive shaft and the exhaust pipe that needs heat dissipation with tape, then proceed with the plastic sealing treatment to avoid affecting the normal heat dissipation and use of these parts after "plastic sealing." To enhance sound insulation and anti-collision effects, secondary spraying treatment is necessary. After the first layer of spray dries, perform the second spray. For new cars, "plastic sealing" is faster due to a cleaner chassis, while old cars require more time, approximately 2 to 3 hours.
After "plastic sealing," whether it's stone impacts or rain and snow erosion, they will no longer cause any harm to the car chassis. The plastic layer can firmly adhere to the chassis, truly offering lifelong benefits from one plastic sealing.
Step 3: Prepare to spray the rust treatment layer. Must first use covering paper (often newspaper) and tape to cover the tires and around the exhaust pipe, especially paying attention to covering the sensors and shock absorbers on the body.
Step 4: Spray the various components of the chassis armor onto the chassis at least 3 layers, with a thickness of about 4 millimeters.
Step 5: Local coating repair, ensuring the best possible coverage;
Step 6: Remove surrounding coverings, clean non-sprayed areas with a dedicated cleaner, wait for it to air dry. A new car takes about an hour, while an old car depends on its condition.
Material, technology, etc., determine the effect
Here we remind those who want to do chassis armor that there are three factors affecting the effect of chassis armor: material is the most critical, construction technology, and whether the beauty shop is legitimate.
Currently, in terms of material selection, larger professional car beauty shops or 4S stores of branded cars have made significant breakthroughs, using rubber sealants instead of materials originally based on oil, paint, and asphalt. They use imported materials such as Henkel, 3M, and ChemiSeal. These products possess excellent characteristics such as high concealment, waterproofing and rust prevention, acid and alkali resistance, heat and cold resistance, elasticity and wear resistance, and being non-toxic and environmentally friendly.
In terms of construction technology, professional beauty shops or 4S stores are more standardized. For selecting places for chassis armor, it is suggested to go to well-known professional car beauty shops or 4S stores of various brands. They offer good service and ensure both materials and technology.
