Spray paint can be used to repair cars, as its primary function is to fix scratches on vehicles. However, its effect differs significantly from that of baked paint. 1. Firstly, the adhesion of spray paint is much weaker compared to baked paint. If low-quality paint is accidentally purchased, the spray paint may peel off within a short period. 2. Secondly, there is a noticeable difference in the paint finish. Spray paint not only has a certain color deviation from the original factory paint but also falls far behind baked paint in terms of gloss. Therefore, if high requirements are placed on the paint finish, spray paint is not the best choice for car repair.

As an average car owner, I've used spray paint to touch up minor scratches on my car. The process is quite simple: first wash and dry the damaged area, then apply the paint in even layers. Applying too much at once can cause runs, so patience with layered application is key. The results are decent - if you get the color match right, it's barely noticeable. However, product batch color variations in the market can be significant, so I recommend comparing with color cards before purchasing. The main advantages are cost and time savings - a can costing just tens of RMB can fix minor issues. The downside? Over time, exposure to weather causes peeling and discoloration, especially for larger damages that won't hold up long. I think it's only suitable for inconspicuous areas or temporary fixes - serious damage still requires professional shops. Best to work in dry, overcast conditions to avoid heat or humidity affecting adhesion.

As an auto modification enthusiast, I can confirm that spray paint works perfectly for small-scale touch-ups. The key is thorough preparation: sand the damaged area until smooth using fine-grit sandpaper in back-and-forth motions, apply primer to enhance adhesion, then spray the base coat. Maintain a 20cm distance while spraying with even, sweeping motions. Color matching is the biggest challenge – different brands have varying gloss levels, so always test on a hidden area first. Having tried several products, some adhere well but oxidize easily. Weather conditions are crucial – high humidity causes bubbling. With proper technique, DIY spray painting can save significant repair costs while teaching valuable skills. Beginners should practice gradually.

Personal experience suggests thinking twice before using spray paint for car touch-ups. While seemingly convenient, it comes with many risks. The color often doesn't match the original paint, making it look cheap, and it tends to crack or peel quickly under sun and wind exposure. I once used it for a minor scratch—it looked okay for the first few weeks but couldn't withstand heavy rain, and after half a year, it looked even worse. The durability is barely acceptable, only serving as a temporary cover. Professional repairs include a clear coat for protection, which spray paint lacks, making it prone to wear. For minor damage, it can serve as an emergency fix, but for major issues, it's better to spend some money at a professional shop for peace of mind. Don't compromise safety to save money, or you might end up with repeated repairs and more hassle later.
