i recently picked up my new MB,as i was looking through the ownners manual i noticed that there was a car care booklet that described how to care for your MB and showed MB car care products formulated for them by meguiars, my sales person got me a discount at the parts department so i got the complete line of them. Very pleased so far with them (3 weeks) i have used meguiars stuff in the past and have to say there stuff is pretty good and SAFE but i believe there are better products.Well to get to the piont I purchased klasse twins at the MB dealer today and got a couple of opinions from two parts people one said i use aio only on my customed pianted el camino every two weeks and use it aio to wash as well great stuff no comparison between klasse and meguiars and the other guy said i would stick with meguiars for your new car wait until your car gets older klasse is a bit to strong for new cars? what do u guys think i really want to use klasse aio not so sure i want to use sg dont really care for shine just protection? how often can i use aio and can i use only aio?what benefits would i get from using sg? What soap and qd should i use with klasse? Can i use klasse on my 3 week old paint that i already waxed with MB paint care? thanks guys one last thing has anybody used vinyl and leather care by klasse?
