Why does the surface of glass fiber reinforced plastic imitation copper Confucius sculpture fade?

The moisture is too high. The copper-like Confucius sculpture made of FRP will fade because of its high water content. Too much water will make the water in the paint layer disperse outward, make the paint film bulge, and lead to the paint falling off the surface. Imitation of copper with glass fiber reinforced plastic is based on glass fiber reinforced plastic sculpture, adding cast copper elements to make its appearance look like a cast copper sculpture, which can basically reach the point of confusing the real with the fake.
