How to Repair Scratches on Hard Plastic Car Parts?

Here are two repair methods: Computer-Matched Paint Spraying Method: This is a rapid technical repair, but it primarily requires accurate color matching and minimizing the repair area. After treatment with special solvents, it enables better blending between the new and old paint surfaces, achieving optimal adhesion. Polishing: When performing polishing, automotive paint care materials must be used. Currently, putty and polishing compounds are generally employed, with polishing compounds being the best material for achieving a mirror-like finish. Polishing compounds are abrasives containing finer particles. The materials used in polishing compounds are categorized into three types: micro-polishing, medium polishing, and deep polishing.
I really enjoy working on my car myself, and scratches on hard plastic interiors are a common issue. For minor scratches, using a heat gun or hair dryer is quite effective, but you need to maintain a proper distance and proceed slowly. The plastic will soften when heated, and at this point, gently press the area around the scratch with a clean cloth to let it naturally smooth out. For deeper scratches, a plastic repair kit is necessary. First, use a cleaner to remove grease, then apply some repair paste to fill the gap, and carefully smooth it out with a scraper. Once completely dry, sand it smooth with wet sandpaper and finish with a coat of plastic renewing spray. This job requires patience, and if you're unsure, it's best to practice on a piece of scrap plastic first. After repair, avoid cleaning with alcohol; instead, use a neutral detergent and a soft cloth for gentle cleaning.
