I purchased a Perma-Bag for my MM. Was shipped directly from Germany. Is is an outdoor cover which you lay on the ground, drive over and zip your car into, like a duffle bag. In addition, relative humidity is kept at 50% through the use of these cannisters with some type of silica pellets inside. This cover is used for storing automobiles during the off season. I will be building a garage on my property next year so I have to take care of the MM best I can. New york City got hit with about 6" of snow today...
