Cold Heat.......it's pretty much an oxymoron.
See what I mean:
civil war, bittersweet, open secret, genuine imitation, smart blonde, drag race,
cold heat, plastic glasses, painless dentistry, freezer burn, pretty ugly, criminal justice.
I saw it advertised too but somehow I don't fully believe it. If you remember several years ago they were selling a wax that would hide scratches. You had to buy the wax that was similar to the color of your car. My Dodge was blue and had several light scratches on the hood. These were not deep scratches but just enough that they were visible up close. Well, I bough the blue wax and put it on then buffed it out when dry. It hid the scratches and looked nice.......for a day or two until the sun bleached the wax to an off-white color and then they REALLY were visible at that time!

Needless to say I tried redoing it several times but it would never last for more than a few days and that was the last time I used that wax. If I wanted the scratches to show up with wax I would have used regular Turtle Wax or Carnuba Wax or something. This is also when you have those doubts about what you see on TV and you realize how true they are sometimes.
