Rusty floor pan!

I've been restoring classic's since 1979, I run the resto part of the shop,The collision and in and out side is run by another guy he uses panel bond all the time, i've tried it but don't like it my opinion!! All my work is butt welded much cleaner and stronger IMO,
For all you old guy's out there remember working on Vette's bonding always coming apart?? So i say do it once and butt weld it, Again my opinion.
Here's a couple pic's of my pan i did at home.
