I was referring to hanging entire replacement panels with the adhesive and that is where I thought you were coming from as well. Patchwork such as you have pictured I would weld also and yes, nice work.
If the adhesives were around back in the day that's how Ma Mopar would have been assembling these cars, I can almost garauntee it!
