A checklist for prepping your car for a needed rest
If you are going to park your E-Type for the winter, not all the following steps are necessary. In that case, you would only have to do steps 1, 3, 5, 10, 13, & 14. However, many people store their cars planning a short stay, but it ends up sitting much longer. These steps are also good for project cars that will not be finished for a few years.
Fill up the gas tank full to prevent condensation. Add a gas preservative additive when the tank is about half full to keep the gas from going bad over time.
Use a product called Engine Fog and spray into the intake of the carbs. It is supposed to coat the cylinder walls with lubricant. Otherwise, a lesser alternative is to pump oil with a pump spray in a mist into the carb intakes until the engine about stalls and then shut it off.
Jack the car up off the ground and put on jack stands to keep from ruining the tires and take the wheels off.
Give the car a good wax job and coat most unpainted and unchromed metals in a light coating of oil.
Disconnect and remove the battery.
Cover the car in a cotton car cover if available.
Drain and replace all fluids including the clutch and brake fluids. (If not silicone brake fluid - you should drain and replace 1x every two years)
Leave it out of gear if a manual and in park if automatic.
Coat the rotors in a fine coating of fluid made for coating brake rotors. Usually in a spray can.
Leave the emergency/parking brake off.
Leave the windows cracked just about 1/2" to allow some air.
Coat and clean all the leather a good leather treatment.
Top off all fluids including radiator fluid.
Take preventative measures for mice/rats by using an ultrasonic repeller, traps, or the like.
