Hi people. Actually, I just wanted to remove an ugly rust spot on the fender … After the dismantling of the left wing I saw that was the extent. I also took down the threshold covering. Luckily only the area in front of the door was affected. The right fender is immediately renewed as this also starts to bloom.. Does anyone know if it can do anything to seal the wheelhouse ? The fender is fixed to the bottom with 2 screws. But there is no opening where water or dirt can get out .. What is the big foam wedge. ? Just for sound insulation ? Would thank you for useful information since Friday the new fenders arrive.
