A while go I had some new tyres on my front Monza's. Later that day I noticed a ring around the wheels which turned out to be a scrape.
I complained to ATS who did the work. The area manager came round to me, had a look and agreed it was their fault. He said something about the protector not working/being used properly.
They sent a mobile wheel repairer around to have a look, he just looked at them and said no chance he could touch them as they were diamond finished.
The chap who did the work ended up with a disciplinary and I ended up with 2 brand new Monza's
Any reputable company should be able to do it without marking the wheels and if they do, they'll sort it..
