The term "white flower" is a phenomenon in which rust occurs in aluminum
(usually called white rust, stains, water stains, and contamination)
In response to acidity and alkalinity, it often occurs in aluminum,
a positive substance Molded parts of the vehicle are seen in models using aluminium alloys and plating

Why use this for imported cars?

Multiple imported vehicle mouldings are used as aluminium alloys (chrome)
90 to 95% of aluminum alloys tested positive by acidity and alkali
High-end imported vehicles incur high costs when replacing parts
(Low cost of parts replacement is low due to plating on cheaper vehicles)
