OA, this particular video has been hashed over at least 100 times. In every case it was noted that the people doing the review did not follow the instructions correctly and in fact where washing their car in direct sunlight. Anyone who has ever washed a car in direct sunlight would know how foolish that is.
They subsequently did another review in which they did follow the instructions and the results were more favorable. If we are going to post things it's only honest to post all follow ups as well, don't you think?
