Hello, yes, I know, a lot has been written about this topic. That’s why I don’t have an overview anymore. In old threads you read again and again that “heated garages” are the safe rust death for cars made of steel sheet. From my point of view not quite understandable. Of course: oxygen and moisture accelerate the corrosion of iron. Heat can probably accelerate this effect somewhat. While “heat” is not comparable to “heat”. The kind of corrosion, which e.g. in acidic (such as road salt) and water accelerate corrosion. This can probably be regarded as safe, as I understand it. Now you read over and over again that it is more harmful to store your car in the garage in winter. In particular, a garage in which a higher temperature than outside prevails is rust-promoting. Heated garages are worst. Does anyone here know about this? I mean ECHT idea, not just hearsay half-knowledge (sorry …)? From my point of view, these prejudices have to be considered: – A higher temperature reduces relative humidity – the air binds more water, thus becomes “dryer”, there is less condensation, which can settle down as water on the sheet. – In a tempered garage there are lower temperature fluctuations. The temperature fluctuations due to the climate changes during the day ensure that the air condensate settles when the air cools at night. It is found on the cars in the morning. But in the invisible cavities the condensation water accumulates the same way. More water = more rust, right? – In the frosty season there is a double effect: in the evening the air cools down, so that water condenses on the sheet metal. Then the temperature drops outside below zero degrees, and the water freezes to ice, which expands thereby and micro cracks in the rust protection layer (lacquer ;-)) expands and deepens, so that more naked sheet metal to the verf all is revealed … As far as my theory … So it would definitely be smarter to put a car in a warm garage especially in winter and not in the carport, which is often propagated as a top solution. Do I miss something? I’m curious what the “rust professionals” say about it …
