Detailing The Chassis "Unibody or Unitbody"

[synoptic12]

This is a brief video upon detailing the undercarriage of the unibody OR unitbody. We believe that this aspect is an important feature. All rubber, plastic , and all boots were lubricated; along with all bushings, metal and aluminum parts. Would any know how to remove oxidized rust from cast aluminum?
