The method to repair scratches on car surface is: 1. Before waxing, the car must be washed thoroughly and kept clean and dry; 2. Use the sponge that comes with the solid car wax to apply the wax. Do not use too much wax, apply it evenly on the paint surface, a thin layer is sufficient; 3. After waxing, wait for 5 to 10 minutes to let the wax dry naturally. The wax should turn slightly white and feel powdery to the touch. The purpose of waxing is to waterproof and protect against acid rain. Due to the protection of the wax, the amount of water droplets adhering to the car body will be significantly reduced, with an effectiveness of 50% to 90%.

I've got plenty of experience with car paint scratch repairs! Just last week I helped my younger brother deal with scratches on his new car. Superficial scratches are the easiest to handle - toothpaste or scratch wax can do the trick: apply it to a soft cloth and buff in circular motions, but don't press too hard to avoid damaging the clear coat. For moderate scratches that expose the base coat, you'll need a touch-up pen - remember to shake the paint well and apply multiple thin layers, waiting 20 minutes between each coat. For deep scratches that reveal bare metal, don't attempt DIY fixes; take it to a professional paint shop immediately. One crucial point often overlooked: always clean the scratched area thoroughly before working on it, as even tiny sand particles can cause more scratches. If the scratch is on plastic bumper parts, it's even simpler - just get a basic touch-up kit for about ten bucks!

The severity of the scratch is crucial for repair. Minor hairline scratches can be concealed with wax, while moderate scratches can be handled by hand polishing with a compound and a sponge pad. Last year, my car got three scratches from tree branches, so I bought a touch-up paint kit with the exact color code—first lightly sanding the area smooth, then filling the dents with putty, and finally spraying the paint. Pay attention to the environment; it's best to work in a dust-free garage and maintain a 30 cm distance while spraying, moving at a steady speed. Remember not to touch the paint after spraying! Last time, I impatiently touched the wet paint and had to redo it twice. If there are deep scratches on metal parts, be sure to check if the metal is exposed; otherwise, rusting through could become a serious issue.

I've taken some detours in fixing scratches and have summarized three tips: First, for the shallowest ones, prepare a microfiber cloth and scratch repair paste, then wipe evenly along the grain for five minutes to see results. For scratches that reveal the white base, clean them first and then apply touch-up paint—it's best to have a nail polish of the same color code for emergencies. Be cautious with spray cans for touch-up paint; practice spraying on a piece of cardboard first to get the hang of the pressure. The key issue is color matching: the color code must be accurate, otherwise the repair will look like a patch. It's advisable to test the color on the inside of the door first. Avoid products that claim to be universal for color touch-ups—they really don't work well. Small areas can be handled by yourself, but for scratches larger than the size of your palm, it's more reliable to go to a body repair and paint shop.

Money-saving scratch repair has its tricks. I once tried using a temporary mix of cigarette ash and cooking oil as a quick substitute for polish. For regular small scratches around door handles, toothpaste paired with an old toothbrush works wonders. The most cost-effective solution is a scratch wax kit under 20 yuan, which includes abrasive compounds and repair sponges, handling about 70% of shallow marks. Important note: Avoid silicone-based products on dark-colored cars as they leave white haze; silver cars show the least visible repairs. For plastic parts, simply use an oil-based marker pen. After treatment, remember to apply regular wax protection—I slacked off on this and new scratches appeared in the same spot within six months.
