continued from previous. (passenger floor welding) 212533, checking and correcting flushness before and after tack welding 215536, butt welding the new panel to the rear floor (also new, installed earlier) 221131, my trick to get the epoxy as best as possible into the weld seam. I modified a spray head with a cleaned straw from an old oil spray can. [ edit 2018: I found out you can just buy these caps with straws over internet) Works better then just spraying and soaking; this gets more paint into the seam. 215635, front floor all welded up & finished. 215749, full view of passenger side front and rear. 223136, welded 2 M8 nuts for additional heat shield (BMW PartNo: 51 48 1 832 850) 220250, heat shield installed.
