what do you mean hard to tell? the deffects have been removed and the direct light sources are what lets you know. not to mention the great reflections in the car.
Meguiars diamond cut compound. now this particular mazda has soft paint. i do not speak for all mazda paint. but in this case i had to use the rotary at low speeds with a meguiars foam cutting pad. i followed up with a cleaner/polish then with another pure polish. after that it was waxed and ready to go. i use a da polisher for my waxes and polishes. with the cleaner polish i used a yellow polishing pad and for the pure polish and wax i used a finishing pad.
