seems like a good product if your at a show and just need to buff your car up a bit after a wash, but my cars always covered in mud, sticky dead insects and bird crap! + waters free and i can get about x20 washes out of a bottle of car shampoo as i said it's the kinda product you'd want if you have to drive to a show/on holiday/ away from home for a few days! good luck to him though!
