Re: Lubing a sliding door
Yes, water resistant heavy duty grease would be my choice. WD40 is more of a temp fix on things that see moisture on a regular basis. A tip: spray the weatherstripping down with silicone spray ($4/can). This will prevent the weatherstripping on the door and on the door frame from sticking in very cold, and very hot weather. It'll also prolong the life of the rubber and create a better seal.
