Just to chime in here,
The scratches that Tech Wax fills in, or the very finest of scratches, usually called cobweb-effect, or spider webs.
It doesn't fill in scratches that have any real depth to them.
If the Tech Wax doesn't hide, or lessen the scratches in your finish, then a paint cleaner, or cleaner/polish needs to be used before application.
Surface prep is key to all waxes, including Tech Wax.
What I found when testing this product was that after buffing out a car, either with a PC, or a rotary, if I applied a wax, (ours, theirs, etc.) or polish/glaze and then pulled the car out into the sun, while it looked better, I could still see cobweb-effect.
If I applied Tech wax, it would fill in most of what other products did not.
So you'll always get your bet results by doing a good job of first removing any scratches or swirls first with paint cleaner or cleaner/polish, and then applying the Tech Wax.
The simpleest combination I found was using a polishing foam pad, like our W-8006, on the PC on a setting of around 4.0 to 5.5 and either #83 Dual-Action Cleaner polish, or ScratchX.
To simply wash a car, then apply the Tech Wax will lessen cobweb-effect, but not completely remove cobweb-effect.
But another thing I liked about the Tech Wax is the gloss, slickness, darkness, and reflectivity.
Some of the cars I have applied this to, the paint just comes out looking wet...
