What to Do If the Car Filler Cracks?

[KevinDella]

Here are the methods to deal with car filler cracks: 1. Locate the area where the car filler has cracked on the body. 2. Use a dry grinder to remove the original paint at the cracked area. 3. Prepare the car filler and apply it to the cracked area, ensuring it blends well with the edges. 4. Smooth the surface with sandpaper. 5. Then, prepare car paint of the same color and spray it evenly over the area where the filler was applied. 6. Once the sprayed paint has completely dried, it is ready for use. Here’s how to prevent car filler from cracking: 1. Choose high-quality filler products when selecting body filler, as low-quality fillers have lower hardness and viscosity and cannot adhere effectively to the car body. 2. Do not add solvents like thinner when using body filler, as this can easily lead to cracking, bubbling, and denting of the paint. 3. Avoid applying the filler too thickly, as thick layers are harder to dry and have poor adhesion. 4. Wait for the filler to dry completely before painting; painting over undried filler will result in poor paint quality.
