From Top to Bottom – Treating the Underside of a 1970 Citroen DS

Preparing a classic car for winter is very important. And, at Bridge Classic Cars we know what it takes to keep your pride and joy safe. Take for example this 1970 Citroen DS21.

This stunning example of the DS has come into us to have the underside cleaned and treated as part of its winter preparation. For this, it isn’t a case of just laying on a thick coat of undersealer. It takes time, attention, care and an understanding of what each individual car requires.

To begin with, Tamas, evaluated the areas that would require cleaning back more than others. Then to protect the wonderful pale French blue paintwork, he covered the bodywork and delicate components with plastic coverings and specific paint tape as to not damage any part of the car. Then, using a variety of steel, brass and copper wire wheels he removed any contaminants/surface issues. After that was removed from the underside and arches of the car (which on the rear must be removed to take the wheel off) Tamas then cleaned down the surfaces thoroughly and carefully to give the chemical treatment in the undersealer the best conditions to work on.

Over many hours, Tamas patiently applied the undersealer to the bottom of the car. Allowing time between each coat for the chemicals in the spray to flash off and begin to cure. This is crucial in order to get the best coverage and more importantly the best protection for the car over the winter.

Then, the car was left to cure with specifically placed heat lamps to make sure that the treatment cured correctly and evenly on the car.
