A lot of the newer stuff is glued together. I never thought I would ever get behind it, but I must admit, there are some wicked adhesives on the market these days.
Examples of this new stuff if I may?
I haven't come across any that have relied solely on glue as what is shown in the diagrams above. Every car I have come across has had other attachment methods involved whether it be spot welds placed throughout or aluminum panels bonded and rivited onto a steel frame. I used quite a bit of it 3m, Fusor, Kent, Duramix, and Sem, all about the same stuff. I have used it to do patch panels as well, and watched the seams raise up over time. It's fast, and less finish work, and why a lot of people like it, but I have moved away from it for the reasons I have posted. I would never glue a roof on as diagrammed lest it sheer off in a rollover. When they pop loose it's usually a large part of the panel. I prefer the 2-component urethane based adhesives that the OEM'S actually do use but it's hard to get them to sell it across a counter. Years of body shop and different training programs have drilled into me to err on the safety and structural integrity/liability side. Biggest uses of adhesives on new stuff is door skins and smc panels and parts when bonding to steel structure. Will it fail every time, no, but it can fail. I know I'm being redundant, and I'm not picking. Just putting some info out so people can make an informed decision as to if and how they would use it. I have seen enough comebacks of my own and others to get past the "it's better than sliced bread " appeal. The stuff says right on it not for structural use.
