Kann man das Teil noch retten?
Hab gestern beim Ölwechsel gemerkt, dass an der Stelle ( evtl. Achs oder Träger ) viel Rost ist. Es löst sich leicht ab. Ist es nur oberflächlich oder schon tief?
Würde es vielleicht polieren lassen und Rostschutzmittel hinzufügen beim Fachmann.
Hello
this is the “normal state” after 3-5 winters with longer stray salt contact
Finished mechanically with a brush, then brushed milky rust converters such as Fertan or Würth/spraying. And so go on for a few months, the rust converter needs moisture/wet and the need time to act.
Then you get 8-10 spray cans fluid film ASR and first of all supply all the voids of the car, the wheel races and the driving chemists with a cavity protection system. Audis are galvanized but the zinc “sacrifices” until it is used up, then the grate comes.
Before winter in the “heissen” autumn, you brush loose rust converters down to steel parts and paint this with Ferpox, Hammerite Epoxy or Brunox EP (Etch Primer) primer or PE chassis lacquer. This takes a few days to dry completely afterwards, the plastic parts are disassembled and the underbody is completely preserved with aluminium parts, scabbards (exterior exhaust system) with permanent plastic spray wax (Berner, Würth, Nigrin, Permafilm, Makra, RotWeiss, 3M). The wax should not be applied to soft “rubber parts” of the axes or cooler tubes if they are not based on rubber.
Thank you very much. Unfortunately, don’t have the means with lifting platform and everything. I wanted to bring it to a person skilled in the art to offer the underbody protection and cavity defeat. But your process sounds more intense and safer. Do you think I’m not supposed to be defeated yet?
As long as you cannot pierce with a screwdriver, everything is good. I’d get rid of the rough, rust converter on it, then fill it with hammerite and finally over it a layer of underbody protection.
This is superficial and at this point not critical.
try to polish.
