Do small particles after touch-up painting need to be treated?

Small particles after touch-up painting need to be treated. The treatment methods are: 1. Perform simple polishing on the car body surface; 2. Squeeze an appropriate amount of wax liquid onto the car body; 3. Use a polishing machine with wax liquid for polishing; 4. Wipe the car body with a towel to make the polished part smoother and brighter. The reasons for small particles after touch-up painting are: 1. The underlying layer was not sanded smooth; 2. The sprayed paint layer was too thin or the construction environment was poor, causing dust to fall after spraying; 3. The paint viscosity was inappropriate, resulting in poor spraying effect. Automotive paint is mainly used to protect the car body from corrosion, and secondly, it can enhance the car's aesthetics, which is a way for most car owners to express their individuality.
Those tiny particles left after the car's touch-up paint job make me extremely uncomfortable. Last time I had a small scratch repaired, the same thing happened - dense little dots that looked like dust got mixed in. If not addressed promptly, they can gradually absorb moisture, causing the paint to bubble or rust, and over time, even the underlying metal won't be protected. Not to mention how it affects the car's overall appearance - driving around like that is downright embarrassing. My advice? Don't hesitate; find a professional to re-sand and repaint it. Spending a few hundred bucks now can save you from depreciation when selling the car later. Choosing a clean, dust-free environment for touch-ups is crucial - I've tried DIY before and often ran into issues myself.
I believe these small particles must be dealt with; don't underestimate them just because they're tiny. Impurities in touch-up paint can corrode the paint surface, gradually expanding the damaged area over time. Once, I saw a neighbor's car suffer from ignoring such minor issues, leading to expensive repairs months later due to peeling paint. Safety and durability come first—neglecting these risks is unwise. Spending a little to have a professional shop re-sand and polish ensures a smooth finish. If the budget is tight, you can lightly sand it yourself with fine sandpaper and apply polishing wax, but avoid doing it in windy areas to prevent making things worse. Remember, prevention is better than cure—clean your tools and environment before the next touch-up.
