回复4楼:不看原文啊，都用了10多年了，自然老化

The lifetime of fiber-reinforced plastic (FRP) depends on various factors, including environmental conditions, chemical exposure, and maintenance. Generally, FRP products can last 20–30 years2, with some fiberglass boats still in use after 60 years

一般玻璃钢自然寿命最少20~30年，好品质可达60年。劣质产品没有说错。
