The quarters have been glued on pickups for a few yrs now, as well as car fenders & quarters. my buddy actually prefers it-no rust issues ever, no distortion.
On newer stuff he's worked on, I've often seen the metal tear before the glue let loose. My next project will get glued on the non-structual stuff. If you can borrow or bargain a dispensing gun it will help, as they are pricey.
