Sorry to drag up an old thread but curious about this stuff... The link about is no good anymore, but I'm guessing the autopia guys are not fans? I must admit it seems like it would be "snake oil" but I googled it and after searching through a dozen pages I have found absolutely no negative reviews from anyone who uses it, just some skepticism from folks who have never actually bought or tried it. I wouldn't expect it to be a replacement for an occasional wash, but some folks literally swear by this stuff as a last step product. I'm wondering if it might be good to have to take care of light soiling/dust after a drive. Anyone here actually use it and NOT like it?
