olaf's oldtimer. repair. Mercedes W201 190D needs some TLC to get rust off the rear window frame.

Today I will take care of some minor oxidation in the area of the lower rear window frame. The challenge is to get the rust off under the seal. I tried a motorized tool "Dremel" to grind it off, but accessibility was a true issue. See for yourself. Maybe a simple grinding paper would have been the easier choice. Whatever change that would have made, the corrosion converter "Fertan" is a super tool. See in the video how it turns rust back into metal again, or at least 100% stops further oxidation. I really like the result.
