hi there , since jellyfish collect the mango jazzie, the windscreen has always been rough , after washing and even claybar the little stuff is still there , it felt like a sharp little sand stuck to it not chips, and when the wiper wipes it the front windscreen you will hear that its not smooth and its running over those grits , i`m afraid that the wiper will be damaged by the gritty stuff on the long run , i`vew read in the search function using the the penknife to scrape the windscreen as if shaving the car`s windscreen, but afraid that it will cause fine lines after the scraping.
any idea out there
