I like the solid seam. as I understand it , the flex in the car is the main cause of cracking at the seams . if you get the welds through out the car done solid, it should make it less prone to cracking. I got a few shots of the trim ring with the common broken bolts issue . the guys fixed it by drilling it out - taping the ring , then installed the bolt using panel bond on the bolt threads ! the top can be finished off for paint and it is a solid repair !!
