A friend's sister's wedding is this weekend and I wanted to get them a detailing kit as a gift. She has a 2002 Acura RSX in silver (maybe metallic silver) and he has a 1998 Honda Prelude in black. Ive read that the Klasse twins are really good on these colors but also have read about the Menzerna twins doing wonders also. The thing that is seperating me from choosing one over the other is price. $40 for the Klasse kit and $70 for the Menzerna kit. What would you choose? I havent used either brands but do have some AIO comming in the mail today.
