Grate points on the W126

Hello friends of 126! I already have some rust spots on my W126. No rusts or something like that, also no particularly large, but nevertheless all around smaller varnish blooms and bubble formations in larger numbers. Throughout typical 126 rust spots. My question, did or did you also have which like you bought your 126er? Who let them go with a specialist and what did you pay for it? Did someone already seal or let grow their underbody? n?? What does this mean in the cut? Are actions that I want to take on in the spring. Now he is standing over the winter in the garage… I would be interested in house numbers… Thank you! MfG SirQuickly
