Cover vehicle persistent

Hi i made a persistent vehicle script, it is not finished yet but im not far from the end, i just need to make the cover removable after the script is restarted, spawn the cover on reboot and save damages. The script is like FlashBack cover system but made by myself, i've never seen something like that anywhere, you can cover a vehicle, mods, position and heading will be saved, you get a notif each time you enter a vehicle in driver's seat and you can remove the cover with qb-target, the cover change depending on the vehicle's class, the cover is at ~80% opacity wich make it easier to differentiate it from gta's props
