Spent the day cleaning mine and after a couple of frustrating hours trying to wax with Mother's Carnauba in the sunlight (no garage, no shade) I ran out and picked up some Turtle Wax ICE paste.
Since it purports that it can be used in direct sunlight I figured this'd do the trick.
But it never dried, only 'congealed' to a gooey consistency that I had a helluva time getting back off (and couldn't use my buffer).
So I waited until sundown and finished up with my carnauba and tossed the nearly new$17 can of ICE in a box, likely never to be used again.
