Gluing Quarter Panels On vs. Welding

I spoke to a couple of paint guys and they suggested gluing on my quarters instead of welding. They say all the new cars use glue, has a 2800 pound strength, seals the edges, and is way easier than welding.

I am doing a driver 71 Barracuda and don't really care that much if it isn't put together exactly as the factory did it.

Anybody have knowledge of using panel adhesive and would you recommend it?

thanks,
Rod
