I remember seeing an infomercial for Turtle Wax Ice when it was first introduced a few years ago.  I must admit, I was a bit skeptical that you could use it in direct sunlight and on plastics (admit it, all of you were too) but after finally buying some of this product all I have to say is WOW.  The results are astounding.  I drive a black Chevy Cobalt, and all of you who drive black cars know how hard they are to wax with conventional waxes.  The first wax this season I used the original Turtle Wax paste and I left little areas of it here and there all over the car that would not come off until I washed it.  With Ice, I don't have this problem.  It goes on clear and stays clear.  It somewhat has the consistency of baby oil.  It's so slick I often drop the bottle several times while going over the car, and have to wash the bottle off with soap and water when I'm finished.  One bottle of Ice will last you a long time.  I have waxed my Cobalt at least 4 times this summer and my Blazer once and I have used only about an ounce of the wax, at this rate this bottle will last at least 4 years.As for repelling water, Ice does an excellent job.  Water easily beads up and rolls off the car.  I can't yet comment on the durability of Ice, as I've used it after just about every wash this summer!  I apply Ice to all the exterior surfaces of my car (except for the glass), it makes the headlights glimmer in the sun and the plastic trim a deep, lustrous black (like when the car was new).  My coworkers are always asking me how I keep my car so shiny.  I even applied it to the taillights of our 2001 Blazer, one of which was a little oxidized, and while it didn't remove the oxidation it did add a little shine so it's not so noticeable.  I would apply Ice to the tires if I thought it would be safe!While Ice is a great product, it isn't perfect and does suffer from some of the same issues all waxes do.  Being that Ice is a new type of wax, it does take a bit of getting used to.  Leaving it on too long can leave a film on the car which will only come off after washing the car.  You seriously only need to leave this wax on no more than 10 minutes!  I found the best way to use Ice is to do sections of the car at a time.I highly recommend Turtle Wax Ice.
