Repair of a rotten arch on a car in 7 minutes.

Repair of a rotten arch on a car in 7 minutes.
In this video I am digesting the rear arch on a BMW E39. I ran into the following inconsistencies, the old arch and the door were very crooked, so when digesting (welding) a new repair kit, I definitely needed a flat door, otherwise everything would have turned out very ugly. I bought a new door on a BMW and put it in the gaps, digested the arch, everything turned out very well.
