I stopped in today and Brian had final fitted the pieces. The fit looks good. He will tack a couple places and panel bond the rest. Bonding seals both metal edges unlike plug welding which leaves exposed raw metal between the welds. They will seam seal also. I asked what they were going to do with the pin holes in the drops. Panel bond again. Tough stuff and ypu have a time window after mating the surfaces to get them lined up just right b/4 it sets up.
