So Meguiar seems to be a pretty good brand from what I read from all of you guys and such.. (I never actually stuck to one brand for my older car...) So is the NXT Series better or the Gold Class Series better? what is the difference? Does it make a difference if my car was black? Oh its a 06 Black Civic Coupe... Since I should really get some of these stuff for keeping my car clean and new... Any thoughts on the two series? Or does anyone have any better combinations interms of washing/waxing.. and everything you need to do...? Thanks =)
