No sand blast .. no acid itching no lifting arrangement .. no com pressure . No water cleaning no mechanical abrasion technique .. they will damage old things . Only putty and painting .. this is not restoration it is repair only
I can't understand much of what is said, but the cars look good. Very basic working conditions and I'm surprised how they get such a good paint finish. Do they use two lack paint? If so I trust they use the proper respiratory equipment. They would likely have a high staff turnover through illness and death otherwise.
