OPERATIONS AT THE DEALERSHIPSTo prevent possible seizure and impossibility of opening the doors when the outside temperature ranges below 0°C, it is recommended to apply PFPE (perfluoropolyether) low-viscosity, fluid-based products grease or synthetic lubricant (such as Krytox made by Dupont or equivalent product), on all the vehicle door housing weatherstrips. When these products are applied on door housings prevent sticking, freezing, noise and ageing; in addition they increase wear resistance in the most strained points and ensure a longer life thanks to the very good load capacity of the lubricating film. Figure 1 below shows the weatherstrips for the side door housing. Fig. 1
