How to Remove Overspray from Car Body?
3 Answers
For overspray that has not completely dried, you can spray cleaner on the overspray and wipe it off with a towel; for dried overspray, you can use 2000-grit polishing sandpaper to grind off the overspray on the paint surface. Below are specific methods for dealing with overspray on cars: 1. For overspray that has not completely dried, spray cleaner on the overspray and wipe it with a soft towel. After wiping the entire car, use detailing clay to scrub the paint surface. 2. For dried overspray, first wash the car thoroughly, then use 2000-grit polishing sandpaper to grind off the overspray on the paint surface. After that, perform a polishing treatment to restore the gloss of the paint surface, and finally, carry out a full paint surface maintenance. The vehicle's paint consists of four layers: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. The electrocoat layer serves to prevent rust and enhance the adhesion of the paint layers. The primer layer connects the basecoat layer and the electrocoat layer. The clearcoat layer is the outermost layer of the paint, primarily functioning to enhance the paint's gloss, improve texture, protect against UV rays, and prevent minor scratches.
With over a decade of car repair experience, I've developed a special method for dealing with overspray. First, use detailing clay with some water to gently wipe, just like erasing pencil marks – avoid pressing too hard to prevent scratching the paint. For stubborn spots, spray dedicated overspray remover on a damp towel, let it sit for two minutes to dissolve, then wipe in circular motions. If the overspray has hardened like tiny stones, it's best to have a professional slowly grind it off with a polisher, as this precision work can easily damage the clear coat if done yourself. Finally, remember to apply wax as a protective barrier to prevent future overspray adhesion. While the clay bar kits used by car washes are effective, you can easily save two hundred bucks doing it yourself – the key is having the patience to work slowly.
My car wash shop deals with this issue daily, and overspray removal depends on the situation. For fresh overspray within half an hour, just use a high-pressure water jet. If it's been over three hours, you'll need oil-based remover. Here's a folk remedy: apply some essential balm on a dry towel and rub gently - this works for most household car paints, but be extra careful with dark-colored paints to avoid leaving marks. For overspray near panel gaps, use a toothpick wrapped with wet wipes to prevent liquid from seeping into crevices. If the affected area exceeds palm-sized, it's better to consult professionals - polishing only costs about a hundred bucks nowadays, while DIY mistakes leading to repainting would cost way more.
