Hello, I hope I ended up in the right subforum. I’m talking about damage limitation! I’ve inherited a 2006 Focus Mk2, which didn’t get much care in his car life. That means the paint is stained, spangled, the plastic parts discoloured and above all: the underbody completely rusted. I’m driving the Focus now exclusively on short distance (10-20 km), TÜV has recently received it again (but for that also rust spots on the mudguard had to be made). Now the question is: how do I get it best? A complete rust treatment etc. is simply not worth it. In the workshop the rust was roughly removed and a protective agent pinned on it, but I see now that this has already been said goodbye (which was also to be expected). The question is above all: wash, so that salt and dirt comes down quickly and does not cause further damage? Do not wash (except rain), so that there is no more water at any places? Especially bzgl. Unterboden is interested in my opinion. The rust spots on the fender etc. I spray with a regular look, but I don’t know about the same thing about fluid.
