Bests & Worsts Reviews from Amazon

Although this picture on the can says "auto / RV" and although Amazon has / had this classified under automotive (probably due to manufacturers picture / categorization) according to the back of the can it is NOT safe to actually store it in your vehicle! Tell me where in the US (or world?) an enclosed vehicle doesn't get above 120F or below 32F??? This is probably a great option for around the home or office - but not a shed or uninsulated garage and definitely not automobiles parked out in the sun! Imagine how exciting that could be to go out to your car on a nice summer day to have it filled with powder or foam!
