For skirting,i will go for Fiber instead of PU..
Bcoz before this when i want to buy a skirting for my car,i had asked several people,n most of them prefer PU..
but after bought the PU,maybe i'm not so lucky,my car lip start to show distortion that cause of hot climate..so now i planning to change it with fiber one..
another experience is my sister's car had been hit n her car sideskirt had cracked..but after repaired,it look like nothing happen..
For me,the only advantage of PU is it flexibility..
