    Models with Galvanized Sheets - Urban Salt Exposure Resistant Cars to Consider

    Most tinsmiths put putty on a bare sheet of metal, some tempe is a nourishment for rust.

    Most tinsmiths do what the customer expects. Cheap and fast. The cost of a decent sheet metal machine would usually exceed the value of the car.

    No, actually painting the sheet with primer after sanding costs a million gold.
    A putty is a sponge, that's how it absorbs moisture.

    It's about time, the foundation has to dry. A typical client will choose what he will do faster.

    Kick the threshold. There you simply cannot see that there is no sheet metal under a thick layer of some sticky paste.


    I'd rather not dig, aesthetics can suffer a lot. Better to look at the threshold with the endoscope. :)

    I know a few VW Bora, where only one of them has no signs of body repairs and nothing rusts ... Import? Course? Maybe someone did maintenance before? I have no idea. Overall, I am still aware of this car as being quite susceptible to corrosion.
    I also know a nice Civic VI and Lanos, both in the hands of one family, used in winter, at least from the outside, nothing but rust. But these are so unusual compared to other copies that I am quoting it only as a curiosity. :)

    Damn, maybe some well-kept or there was no time for him yet?

    This is the old school of putting putty only on a blank sheet of metal.
    Apart from the fact that it is a bit too vulgar, I agree. Any chipping, padding and putty drinks water. An epoxy primer should fairly effectively retard or stop corrosion of the sheet in such a situation.

    I'm looking for a car and I'm wondering whether to target models with galvanized sheets

    I propose to go to the specifics: what segment are you interested in and for what money. Yes, this is talking in vain.

    And the discussion was basically about which popular models are well galvanized .

    I know one that disappeared in the eyes of the thresholds, just a factory defect, moisture / water collected, etc.

    It is enough that the runoff from the sunroof comes out and all the water lands in the sill and the floor inside.
    Those without a sunroof rot more slowly.

    Indeed, I did not notice when the topic was founded. In my opinion, a sterile discussion.

    Well, not necessarily, you can always share knowledge and experience.

    My 2 renouns from the time I have them, that is 9 and 2 years, are under the cloud, and they are like new in those places.

    For information - in the Golf IV estate (1999) I had a problem with the corrosion of the tailgate (lower part of the window) and with the front fenders. These fenders were rotting above the wheel and at the lowest point, i.e. on the side of the door pillar. It turned out that a sponge insert in the form of a wedge is to blame for this, attached between the wheel arch and the fender. As you know, the sponge is constantly wet and causes corrosion. After disassembling the wheel arch, I threw the sponge away. At the point of contact between the wheel arch and the door pillar, i.e. in the lowest place (on both sides of the car), I dumped about 1 kg of mud and sand, which kept moisture constantly. After removing dirt and rust, I preserved these places by stopping corrosion for some time. I poured oil into the thresholds from time to time.

    Reno Scenic 2 (from 03 to 09) is galvanized, it does not rust at all, I don't know about other years.

    Someone wrote that Skoda has good sheet metal. I have a 2004 Fabia, it has never been beaten, and holes have appeared under the door handles and under the registration light. I think that's a bad indication of corrosion protection.

    I think you can't just write in terms of brand, but models and vintages.
    I have recently bought an Audi A4 B5, a car almost 25 years old, the underside of the car is practically corrosion free apart from the rear beam, the car has not been particularly well cared for, it just looks like it has been thoroughly rinsed of mud from time to time, the garage supposedly hasn't seen it for years. In comparison, the A3 8L, which is 2 years younger, looks worse and had to be spot cleaned and maintained.

    Peugeot 307 year 2004, my other Eurovan (Fiat Ulysses, Citroen C8, Peugeot 807) Lancia Phedra year 2008- zero rust on patch and undercarriage.
    Both from new with me, not maintained.

    It's not bad or even good, just look at how many of these are on the streets and that's it, and the wing issue is also down to the abandonment of the big runoff in the wheel arches, the B5 doesn't have that anymore and it pits, just like the 8L - you have to flush out the sand carefully on a regular basis.
    Of course, no car can keep thick layers of mud in nooks and crannies, under plastics unscathed, and that's where even the most corrosion-resistant steel chariot will eventually corrode, and with salt, I have my doubts that aluminium (e.g. A8) will still hold up for long years either.

Topic summary

Galvanized steel sheets provide a form of corrosion protection by coating the metal with zinc, which sacrificially dissolves to protect the underlying steel. However, the effectiveness depends on the thickness and application method of the zinc layer, with hot-dip galvanization offering superior protection, though it is mainly used on automotive frames. Corrosion resistance also relies heavily on the quality of the base steel, paint coatings, water drainage design, and maintenance practices. Common issues arise from poor repairs, accumulation of moisture and debris in wheel arches and thresholds, and damage to protective coatings. Several car models and brands are noted for using galvanized sheets, especially from the late 1990s onward. Notably, FIAT passenger cars produced in Italy and Poland (except Uno) from the mid-1990s are galvanized. Skoda models such as Octavia (1, 2, and 2FL), Fabia, and newer Superb and Roomster feature galvanized sheets with additional plastic coatings for rust prevention. Volkswagen Golf IV has been fully galvanized since its production start, though some threshold corrosion issues have been reported due to factory defects or post-collision repairs. Audi models from the mid-1980s (C3, C4, B3, B4) and early 1990s B4 vintages show good corrosion resistance, while later B5 models have mixed results. Peugeot 405 and 406, Citroen Xsara II, and Renault Scenic 2 (2003-2009) are also recognized for good corrosion protection. Maintenance such as regular cleaning of mud and sand from critical areas and oiling thresholds can prolong sheet metal life. Despite galvanization, rust can still occur if the zinc layer is thin, damaged, or if repairs are improperly done with putty that absorbs moisture. Overall, galvanized sheets improve urban salt exposure resistance but must be complemented by quality materials, design, and upkeep.
