I have a separate building that is 16"x10" that houses all the yard stuff, mower, shovels, wheelbarrows, etc. I told the wife, the garage is meant ONLY for cars and and car stuff.
I have a California Car Cover on my car as well as Marine grade(the green) Sta-Bil in the tank.Also have a Battery Tender on the battery. Was told the marine grade works better for longer periods of time. Have been using it now 3 years with no start up problems in the spring.
