I am planning to clean up the undercarriage of my 66 Coupe deVille during the long winter months. The car is in fantastic condition. There is still the original undercoating on the car. In areas where it was not applied there is some slight surface rust which I would like to remove and conserve everything.

To make the car perfect again I will also dry ice blast the undercarriage and totally clean it up like I did on my 74 and the Roadmaster to preserve it as good as possible.
Today I started to brush some of the surface rust away. After that I will apply some rust remover.
I took some "before" pictures and a video.

Its a very long and dirty job to do it right
