Why is the black plastic part on the outside of the Tianyi A-pillar fading?
2 Answers
The fading of the black plastic part on the outside of the Tianyi A-pillar may be due to the plastic yarn tube discoloring after sun exposure. You can use dashboard wax, coating care agents, or shoe polish to address this issue. Using Dashboard Wax: Dashboard wax is typically used for polishing instrument panels or plastic parts. Applying it to faded external plastic is both time-saving and effortless. Using Coating Care Agents: Coating care agents can produce excellent results on plastic parts. They are effective for restoring faded or dull plastic surfaces. Using Shoe Polish to Conceal: For black plastic parts that have turned white, black shoe polish works well and is convenient to use.
I've given a lot of thought to the fading issue with the black plastic trim on the Tianyi's A-pillar. Sun exposure is the most common cause of plastic discoloration, as UV rays break down the pigments—especially when parking outdoors in summer, where black turning gray over time is a frequent problem. Using the wrong car wash products can also be damaging; for instance, cleaners containing alcohol or strong acids can corrode the plastic surface. Environmental factors play a role too—urban dust and pollutants in rainwater can accelerate plastic aging when they repeatedly adhere to it. I recommend using a professional plastic restorer for polishing, which works quite well. If the damage is severe, it's best to replace the part at a service center. For daily care, try parking in shaded areas to avoid direct sunlight and extend the part's lifespan. Long-term car ownership requires attention to these details.
