just came in from cleaning off the car, it's now snowing just a little, and better half suggested that it would be a good idea to get the ice off before it got covered up......so i went out to start the car so i could run the defroster and rear window heater so the ice would come off easier, that is somewhere between 1/4-3/8 of an inch of ice, but first you must open the door, after about 5 minutes of chipping ice i managed that normally easy process.......got it all cleaned off but even with the heaters running involved a lot of effort.......
