As such, I don't see a need for frame saver aerosols, beyond a spritz of WD40 and greasing of all inserted parts, figuring they'll last my lifetime at least.

I am far more concerned with surface rust and paint bubbling, particularly if the bike may have been used during the winter (salt) months or at the Joisey shore and skip most frames with material issues. In rare instances I treat most scrapes and kickstand damaged areas accordingly with nail polish or enamel.
