i personally dont like the local turtle waxes..maybe they are not real, they are always extremely hard to come off, both wax and polishes and even the cleaner waxes.
the turtles which you could see in the picture above are imported a while back and they work like a charm, though i dont use them anymore.
3M perfect it is a rubbing compound, could be used wit both hands and machine..cleans away fine scratches in a jiffy.
Nu finish car polish is something which i dont use too often, it is usually for old cars, since i dont have any car which has quiet an old paint, so i dont use it, used it once though on my datsun, before it was given a new shade..it really cleans the paint, but it would eat your clear coat in seconds if you use it too much and too rigidly.
meguiar's is the best thing ive ever owned so far..excellent product, but you have to make sure that you use a clean applying pad, otherwise you'd find it really hard to apply..it comes off really easily..and gives the perfect shine and a wet look..its a pure carnauba wax, and if you want a show car finish you could use other on top detailers from meguiars and mothers..would be cherry on top.
