Hello community, I have to remove rust at my daily (Megane 2 Grand Tour BJ 2006 – 234tkm) at the thresholdrs as well as at the rear wheel runs. At the wheel runs at the rear there is minimal rust (very many stone strokes which have set minimal rust). The thresholdrs look optically in the front area already worse. The varnish + primer is off by enormous stone stroke I think (looks like sand blasted). There – God’s thanks only superficial rust has accumulated. ubstanz is still very good – there are of course no holes. Therefore, remove rust well, prime, paint. My question would be now. Which primer should I use best? Can you give me some tips about anti-rust primer which product is useful? Must of course be overpaintable. Greetings & thanks in advance, Michael
