There you are nicely ready.
Currently, the old paint of the famous Bridge in Rotterdam removed. That removal is done with grit blasting, or small stones under high pressure against the bridge to be blown, and so the old paint off barns.
The cars on the south side of the bridge parked unfortunately, damage incurred, and that is because something went wrong with the treatment. The stones are normally namely collected, but in this case they were by the machine to the outside blown. Indeed, right at the parked cars.
In total were about 200 cars damaged. The iron particles attach themselves to the paint, causing it to feel like sandpaper. Affected people can report to the contractor that a suitable solution will offer.
More high-profile examples of the damage? Check out this Skyline R34 with acid was treated or this Audi A4 that is a terpentinedouche got. Notice the great number of comments.
