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.
