Thank you for the informative and detailed post .

? Could you elaborate on the evaporust stuff a little bit ? .

I've been using a dilute Phosphoric Acid mix of a few decades now but I've seen the Oxalic Acid and wondered if it was too strong, if you're using it in aluminum I'd think not .

? Can't you shim the rattly lower tabs with thin rubber or something ? .
