Recently I had my Honda (see signature) during the lunch break on the lift to find a noise. I used the opportunity to inspect the underbody and also to make a few mobile phone pictures. The car was partly sandblasted two years ago and treated with Mercasol underbody protection. Now I see, among other things, behind the petrol tank and over some crosscarriers light approaches of aerial rust. Everything looks quite harmless, in my opinion – see appendix – but w Do you have to intervene here? Normally I would try to go over there with some sandpaper, then brush in with rust converter, and possibly oil a bit after drying. However, it is difficult to access and time I don’t have any… Lieb Gruss Oli
