When i installed the optional footrests, i realized that my bodyshop left some of the floorpan area “unfinished”. And i thought if i bring the car for blasting and a layer of primer soon anyway, i better make sure it looks a bit nicer underneath that primer layer.
So i took the old angle-grinder out with a sanding disk and started to grind down those welds. I’m not a professional metal guy so this will have to do for now. at least everything feels smooth and looks much better than it did before and that without doing any further damage.
