DIY Tips to Repair Your Car Scratches

It is inevitable for cars to be scratched when driving. Scratches affect the car’s appearance and cost a lot of money to repair. So if you master some car scratch repair tips, you can save a lot of money. Let’s take a look at how to beautify and repair these small defects!

Tiny scratches

First aid products: fine wax, coarse wax

The slightly scratched paint surface damage is on the surface of the topcoat, which can be completely repaired by waxing. Treat it with a mixture. The method of wiping is straight wiping and then waxing. You can use coarse wax first, then fine wax, in the same direction from the inside to the outside, so that the fine scratches are almost removed. Of course, there is a more cost-effective way to repair with toothpaste by lightly applying to the shallow scratches and then using a soft cotton cloth to wipe counterclockwise for several times to reduce the scratches and avoid air erosion on the scratches.

Scratches that cannot see primer

First aid products: fine wax, touch-up pen

Slightly larger scratches can be rescued with paint pen. Paint touch-up pens are sold in general auto supply stores. After the owners report their car model and official color name, they can buy touch-up pens with the appropriate color number. Shake the paint in the touch-up pen well before use and make up the primer like nail polish. You can add a certain amount of thinner to the touch-up pen so that it can be sprayed smoothly. Carefully spray the area that needs to be repaired. After the lacquer brush is dry, apply fine wax.

Scratches that can see primer

First aid products: de-marking and anti-rust agent, self-painting

For severe scratches, if you can see the color of the lower primer, it depends on the area of the scar. Generally, bumpers, rearview mirrors and the wheel eyebrows of some cars are made of engineering plastics and will not rust. Whether to touch up the paint depends on the owner’s request. But if these severe scars appear on other parts of the car body, it needs to be painted, otherwise even a small damage, the steel plate will begin to rust. By then, even painted, it will be difficult to prevent rust. The owner can wash and dry the car first, apply rust remover to the scratched area and wait 10 to 15 minutes to wipe off the rust with tissue paper to avoid the scratched area to continue to rust.

Scratch dent treatment

First aid products: dent repair technology

If the scratches and dents left by the car surface after a collision do not appear to fall off or paint off, the perfect repair effect can be achieved through the dent repair technology. It takes about 20-40 minutes, which greatly reduces the cost (about 50% of traditional sheet metal and spray paint) and will never deform or fade. The tools needed for repairing are not complicated. The crowbar is mainly used to push the steel plate that has been sunken in from the inside to the outside. This technique must be delicate and fine-tuning, and then use a rubber hammer from the outside to the inside. Knock it to repair the overall shape and finally use a sharp object like a pencil to fine-tune the convexity of the car body.

Bumper scars

First aid products: special chemical synthetic agent

If the bumper is only slightly scratched, it is not a major problem. But if it is full of scars and ugly, it is necessary to find a way to repair it. The owner can repair the bumper with a special chemical synthetic agent, which is very easy to operate for anyone. The car owner should cut off the burrs on the bumper first, preferably with a knife and then apply putty on the potholes to make it smooth. Prepare putty close to the color of the bumper. The putty is mixed with the main ash agent and hardener. Use a spatula to coat the putty. The trick is to embed the scars. After the putty is firm for 2-3 hours, sand it with water and sandpaper and spray paint a week later.
