Your attention to detail is phenomenal. Are you from Japanese or German ancestry?
Anyway, one of my specialties is “Finish” work. I suggest you take a look at reapplying a clear coat finish to all of the aluminum pieces you cleaned and shined? There’s some really bombproof urethanes out there that hold up for years against the most corrosive elements, i.e., salt, snow, etc.
I think it will eliminate a lot of the elbow grease that will otherwise be needed to maintain the aluminums new factory appearance.
