Car polishing requires: a polishing machine, clay bar or decontamination pad, wool pads and foam pads, various types of polishing compounds. Car polishing involves using a polishing machine with polishing pads and compounds to uniformly grind the car's paint surface. It primarily relies on the cutting force of the polishing pad and the fine particles in the compound to heat and soften the paint, allowing the surrounding paint to fill in scratches. This process results in a smooth and glossy finish where scratches become invisible. If your car needs polishing, it is recommended to visit a professional auto detailing shop. Achieving good results without a polishing machine is difficult, and improper operation may damage the car's paint surface.

Polishing a car requires several essential tools. First, you'll need a polisher—I recommend beginners start with a DA (dual-action) type for safety and to avoid burning the paint. Next, select polishing pads: purchase a few each of coarse, medium, and fine varieties, such as wool pads for deep scratches and foam pads for achieving a mirror finish. Polishing compounds come in three stages: cutting compound for removing scratches, medium-cut compound for transitioning, and finishing compound for enhancing shine. Don't forget the accessories: painter's tape to protect plastic trim, microfiber towels to wipe away residual dust, and a spray bottle to keep the surface cool with water. Beginners should keep the pad moist, avoid speeds exceeding 2500 RPM to prevent overheating and damaging the paint. Finally, use a degreaser for thorough cleaning before applying protective wax.

I often do DIY polishing, and the basic tools include: a dual-action polisher or hand polishing pads, with three types of polishing discs prepared—coarse, medium, and fine. Use a yellow cutting pad to address scratches and a black finishing pad for shine. Opting for an all-in-one polishing compound makes the job easier. Essential protective gear includes safety goggles, a dust mask, and long gloves. Also, keep several buckets of clean water handy to rinse and cool the surface while polishing, and use microfiber towels to dry it promptly. A handy tip: thoroughly wash the car and remove iron particles before polishing, and always degrease before waxing afterward, as residues can affect the shine. Choose a cool, well-ventilated area for polishing, as direct sunlight can cause swirl marks.

As a professional, I believe the key equipment for professional polishing is a vertical polisher paired with a 6-inch polishing pad. For consumables: use a wool pad for coarse cutting, a hybrid pad for medium cutting, and a fine foam pad for mirror finishing. Matching agents require water-based polishing paste, which is eco-friendly and easy to rinse. Basic materials also include masking tape, an air gun for debris removal, and non-woven cloth. Key tips: choose soft pads for dark-colored cars to prevent glare, while universal pads work for light-colored cars; maintain slow and even movement of the pad; promptly clean paste residue to avoid secondary scratches. Finally, it's essential to use a paint cleaner to remove the oil layer.
