I am going to be patching a lower quarter on my other project, a 60 Chrysler Imperial. I have heard that panel adhesive (like what 3M makes) is supposed to be as or almost as strong as welding. I can't argue with that because I have never used it. It sure has a certain appeal to me, especially not worrying about warping the panel, etc. What are your experiences with using adhesive for patch panels? Are there certain panels where adhesive would be better? or worse?
