hello, i seen how you did this and what guide lines do you have to follow in japan while doing major structural work like this? I can tell you've been doing this for a while. In the video when you were taking breaks from recording did you use a tram gauge to square out the door opening? Did you section in the piece of the inner reinforcement on the B pillar? It looks very nice and the use of weld thru primer was a good touch and cavity wax would do it some good since the humidity eats at all the cars.
I would have walked away from this kind of purchase/repair, take a long time to fix but its cheep then why not. Great job, but you can see difference in color on the damaged side from hood to the back door must of stooped in the middle of the paint job or two mix jobs. Still a weary good job.
