AAA will do her better then that slime crap!
And they will unlock her car when she locks her keys in it, along with giving her a gallon of gas when she runs out of it, and jump the battery when she leaves the lights on all night!
Green slime is great for the small things like lawn mowers and other light farm equipment, but just a sales gimmick for cars. I know of some tire shops that when they unscrew your valve stem and green stuff come out they screw it back in and send you on your way to a different shop, they just hate the stuff!
But serious, peace of mind = AAA
