Was BSing with a buddy and got taking about the use of adhesives in new car assembly and was wondering what kind of DIY options/uses there are.
Could you use an adhesive to stitch weld a chassis or replace a floor pan?

The same products used in new car assembly are available where ever auto body supplies are sold. The packaging is a siamese twin tube with a disposable mixing nozzle and a twin plunger "caulking gun"
In reply to TurnerX19 :
What are they typically used for in DIY projects?
Adhesives? Forget DIY -- what are they used for in OE??
3M panelbond. Yes you could use it to replace a floorpan, but you would get no benefit in using it to attempt to stitch weld a chassis, as it merely bonds, it wouldn't provide the structural rigidity.
If memory serves, we used hysol in FSAE. Great stuff, not cheap.
If you are on a McBudget you can use Liquid Nails.
The epoxy eastwood sells seems similar to jb weld. It worked for my small patch repair project
I'm guilty of being an engineer, I'd look for things like this to decide. A little google fu and the home hobbyist can get the good stuff these days.
3M panel bond has been utilized to "repair" e46 m3 rear subframe tearing in multiple accounts.
I would think it would not be very good for trying to get the effects of stitch welding, because when the OEs do that, they bond the panels together before welding. (As was explained to me) Trying to wedge adhesive into an already welded together gap would just give a similar effect as seam sealing.
I used the 3m panel bond to cover the hole in my roof after removing the sunroof. Plus rivets every six inches. Could probably pull the rivets now if I wanted.
Hey, we just posted a Classic Motorsports video about this very topic: How to glue on a quarter panel.
Just like any other joint, you must design it properly for the job it has to do.
For adhesive, the bonded surface area, the types of loading (shear, tension, comprsssion, torsion).
Peel strength, operating environment, temperature, flexure/deformation of the base materials, etc.
Then there is the application process and methodology .
