190sl Lower Firewall Repair
The right lower firewall had previously been repaired without much success. The fabricated panel had been lap welded, which would in the future cause a water trap and further rust problems. In addition to this the old panels were not de-rusted.
The only way forward was to cut this out to sound metal and butt weld a replacement panel.An air cut off tool was used to cut out the rusted panel. A paper template was made and transfered to the new reproduction panel. The usual tip of measure twice and cut once was adopted in order to ensure correct fitment first time. This was then given a slight tappered edge to assist strenghting the weld and coated with a weld through primer.
