Time for some slight rust removal and applying of wax/oil protection on the underside of the car. I've been looking around at where to do a "hohlraumbehandlung" and a "unterbodenbehandlung" in Zurich but it seems like there are no specialized garages for this?
I found one
but they haven't responded to my email I sent two weeks ago and no one picks up the phone. I found another on the other side of the border but it's quite a stretch as it is past Stuttgart..
Does anyone have recommendation in the Zurich/Winterthur larger area for this? Would be highly appreciated.
