When the bumper is scratched and the plastic is exposed, the repair methods are: 1. Toothpaste. Use toothpaste for repair as it has a grinding function that can effectively restore the surface; 2. Touch-up paint pen. A touch-up paint pen can cover small and shallow scratches, making the marks less noticeable; 3. Car paint scratch remover. This product also repairs bumper scratches, functioning similarly to toothpaste with its grinding properties to quickly restore the damaged paint area, though it only works for minor marks.

A few days ago, my car also scraped against a wall corner, exposing the plastic of the bumper. I quickly took matters into my own hands to fix it. First, I bought a car bumper touch-up paint kit online for less than a hundred yuan. The steps were simple: first, sand the edges of the scrape smooth and remove debris, then fill the dent with putty and wait for it to dry, followed by light sanding to smooth it out. Finally, spray on the original color paint and cover it with a clear coat for protection. The whole process was done in my home garage, saving the cost of going to a repair shop. Here’s a little tip: when spraying paint, apply thin layers multiple times to avoid drips; let it dry for a full day before washing the car. Remember, if the scratch is too deep or covers a large area, it’s best to seek professional help, as the plastic can become brittle over time. Also, when parking, avoid getting too close to obstacles, and regularly waxing can help protect the bumper.

What is the correct shutdown sequence for an automatic transmission vehicle?

The correct shutdown and parking sequence is as follows: 1. Straighten the steering wheel. 2. Turn off all electrical equipment in the vehicle, including all windows, sunroof, etc. 3. Press the brake pedal and shift the gear to N (Neutral). 4. Engage the handbrake, shift to P (Park), release the brake pedal, and turn the key to shut off the engine. Whether shutting down in P or N gear, always engage the handbrake firmly before releasing the foot brake. Only the handbrake can truly prevent the vehicle from moving. The P gear functions similarly to engaging first gear in a manual transmission to prevent rolling. If parking on a slope, first shift to N, then press the brake, engage the handbrake, wait for the vehicle to stabilize, shift to P, release the foot brake, and finally turn off the engine. If P gear is engaged first, it means the P gear is acting as the brake, and the handbrake's braking effect is essentially ineffective.
