i wax my car almost every week, im pretty sure i know how to do it right since ive done it to all my car's; its just a personal experience, it always leaves streak marks, i can really tell in my carbon fiber hood, specially if its not cold. in my black integra i wouldnt even dare to put it on from the moment i tried it once i saw streaks everywhere.

But either way, everyone has personal opinions, you wont really find one you like unless you go out and try a few.
