Car paint peeling is usually caused by external damage, defects in the spraying process, or environmental erosion. Physical impacts such as scratches and stone chips during daily driving can directly damage the paint structure. If the primer is improperly treated or expired paint is used during repairs, reduced adhesion may lead to secondary peeling. Excessive sulfur and phosphorus impurities in body panels can trigger electrochemical corrosion, causing the paint layer to detach. Prolonged sun exposure accelerates paint aging, while acid rain and improper car washing (such as using stiff brushes or strongly acidic/alkaline cleaners) can erode the clear coat. For minor peeling, a touch-up pen may be used after thorough cleaning of the affected area. If primer is exposed or rust is present, professional sanding followed by respraying of primer, base coat, and clear coat is necessary—preferably performed in a dust-free paint booth for optimal results. For routine maintenance, avoid washing under direct sunlight. Monthly waxing enhances UV resistance, and shaded parking is recommended. Rinse the vehicle promptly after rainy seasons to remove acidic residues. Note that original factory paint undergoes high-temperature curing, offering superior adhesion compared to aftermarket repairs. Thus, polishing is advised for minor scratches rather than immediate repainting. If extensive non-collision peeling occurs within five years of purchase, potential manufacturing defects should be evaluated by the dealer for warranty coverage.

For the repair of minor car paint scratches, different methods can be chosen according to the degree of damage. For slight clear coat scratches, toothpaste without abrasive particles or scratch wax can be used. First, clean and dry the damaged area, then gently wipe it in a circular motion until the scratches fade. If the scratch has exposed the primer, a touch-up pen matching the car body color is required. Before application, test the color in an inconspicuous area to ensure it matches. When applying, maintain uniform thickness, and polish with fine car wax after drying. For deeper scratches, it is recommended to first sand the surface smooth with sandpaper, clean it, then fill it with specialized car paint putty or filler, and finally perform localized touch-up painting. If the damaged area is extensive or involves the metal layer, treat the exposed part promptly with a rust inhibitor and consider visiting a professional repair shop for computer-matched color and spray-baking processes to ensure color consistency and rust prevention. When parking daily, avoid environments prone to scratches such as tree branches, and regular waxing can enhance the paint's protective layer.

The cost of car painting is influenced by factors such as vehicle model, paint type, painting area, and repair channel, with prices ranging from a few hundred to tens of thousands of ringgit. For ordinary small cars, partial painting of one panel costs approximately 200 to 800 ringgit, while a full-car paint job ranges from 2000 to 3000 ringgit. Medium-sized cars typically incur 400 to 1500 ringgit for partial painting and around 5000 ringgit for a full-car repaint. High-end models may require 1000 to 5000 ringgit for partial painting and 6000 to 15000 ringgit for a complete paint job. Metallic paint is 10% to 30% more expensive than standard paint, with specialty finishes like pearl paint commanding even higher prices. 4S dealerships charge premium rates due to OEM paint materials and standardized processes, with partial painting starting at 300 ringgit and full-car painting beginning at 4500 ringgit. Professional auto repair shops generally offer 15% to 20% lower prices than 4S stores, while roadside workshops may charge about 100 ringgit for minor scratch repairs, though their workmanship quality varies significantly. Additional costs apply for sheet metal repairs: minor dents start at 50 ringgit, while severe deformation may cost hundreds. Large or complex areas like the engine hood or roof have a minimum single-panel painting cost of 500 ringgit, whereas a door half-panel repaint averages 300 ringgit. Car owners are advised to prioritize service providers with proven craftsmanship quality based on their vehicle's value and budget, and to obtain precise quotes by consulting authorized local service centers.

There are various cost-effective methods to address minor car scratches. First, touch-up pens can be used for spot repairs. Ensure the color matches the vehicle's paint and that the scratched area is cleaned and dried beforehand. For superficial scratches not exposing the primer, use toothpaste containing abrasives or specialized scratch repair compounds. Apply with a damp cloth using straight, unidirectional strokes to avoid circular motions that may cause further damage. For scratches with oxidized rust, first gently sand with 2000-grit wet sandpaper, then apply a sealant or car wax for protection. Nail polish can serve as a temporary solution; choose a matching shade to evenly cover the scratch, providing rust prevention. For deeper scratches not reaching the metal layer, employ a "coarse-to-fine" wax polishing method: polish linearly with a compound before waxing to restore shine. Small dents on plastic components like bumpers can be filled with putty and sanded smooth. Note these methods only apply to minor damage. If scratches penetrate the clear coat or expose bare metal, promptly visit a professional auto body shop for primer treatment and spot painting to prevent rust from moisture exposure. When parking, avoid contact with sharp objects like branches, and regular waxing helps prevent minor scratches.

The repair method for vehicle paint chipping should be selected based on the extent of damage. For minor paint chips, a touch-up pen can be used. The surface must be cleaned and a matching color selected, though color discrepancies may occur. For slightly larger areas of paint damage, spray paint is recommended. The surface should first be sanded to improve adhesion, followed by thin, layered applications. If the damage has reached the primer or covers a large area, professional repainting services are advised. The process involves sanding, applying putty, masking, multi-layer painting, and baking to ensure quality results. For plastic parts, a specialized primer should be used to enhance paint adhesion. As temporary solutions, non-abrasive toothpaste or car wax can polish minor scratches, or decorative stickers may conceal them. Avoid car washes or exposure to corrosive substances for 48 hours post-repair. To prolong paint longevity, minimize parking in direct sunlight or humid conditions. Professional repainting costs approximately RM300 and up, depending on damage size and vehicle model. Paint defects caused by manufacturing issues during the 4S dealership warranty period may qualify for complimentary repair.
