I have a bottle of polish and wax from meguairs since summer of 2002. It gets over 120 degrees inside my garage in the summer here in florida. Will the heat and cold mess the ingredients of the product? I have hi-tec yellow wax #26 and mirrow glaze swirl remover, but I keep that in a bag in my closet. My question is, if you store wax and polish in your garage how long will the product still be good for, or it doesn't matter?
