Before your winter weather dips into the freezing zone, spray some WD-40 onto a soft cloth or paper towel and wipe liberally on all your car door and trunk seals to prevent them from freezing closed. Also, take your WD-40 can with the little "straw" attached to the sprayer, and liberally spray it into all your car door and trunk locks. The WD-40 will not hurt your car's paint finish, but you should wipe off the excess. This one application on the seals and in the locks usually doesn't last for the whole season, so you may have to reapply. For emergencies, I always keep a very small can of lock de-icer in my purse. - Tori
Won't WD40 deteriorate the seals? (12/04/2008)
