Used to put my car through my ARC car wash about 2/3 times a week with no issue at all...........
And now i dont run the site anymore, i put it through my mates ARC car wash once per week instead
Different wash systems have different setups, the ARC/IMO ones are setup so the operator can press a button at the front and lift the roof brush up to clear any obstacles, although in mine and my mates sites, the ZS spoiler was complete fine without lifting it.
