Got accurate duplicates made and installed. Originals resting at home in pristine condition. The original plates had started to rust even at home (Islamabad plates). Painted the backsides and locked them at home. In 4 years of driving in Karachi, Islamabad, Rawalpindi, Lahore, Murree no one has stopped me. I might be breaking the law but there is no mechanism to stop licence plate damage, theft, discolouration etc.
