To check if there was no hidden rust underneath the other sound proofing I took everything out. Luckily everything apart from the seat mounts was perfect.





























The metal box for the aircon vaporizer is also welded on and sealed.

















I also took a closer look at the rust spots at front seat mounts. The rust seems to be exactly where the edges of the seat mounts rest on (green line). I first thought the mount would rub on the floor, but the carpet is still in between.
