Reply to "Need Advice on Adhesives: LIONEL 15"aluminum passenger car plaques falling off"

I have had this issue with a few older Lionel aluminum cars. Cryano adhesives (SuperGlue and the like) are not a good choice because although they stick pretty much immediately, the name plates won't stand up to handling because the glue is fairly brittle. "Goo" or any similar household adhesive (including Elmer's) is a better bet because it has some flexibility. For that reason, I once used contact cement for this specific purpose, but the threads it almost always creates are a nuisance although they can be removed from anodized aluminum by common solvents.
