My experience with waxes has firmly convinced me that the Mothers (and other) waxes are simply not long lasting for our environment.
I rate the NXT 2.0 the highest, its shine is deep and long lasting.
As far as paint swirls go on your Civic, you need to trust me on this, I have done compounds and rubbing on my cars, my friends cars, if you use the right product, the amount of clear coat taken off is not even measurable.
My suggestion is that you use something similar like 3Ms Perfect-it, by hand... if you use it by hand very little abrasion is possible. Then apply SwirlX before a wax to mask swirls and finally TechWax and see the result.
While this wont get rid of swirls (unless you go the machining route once), it will deeply mask them.
