AIO will work in pretty well if you give it some time. The more you work it (allow it to buff out), the less wiping you will have and the better the resulting finish (durability and gloss).
Many people have commented the AIO is a polish/cleaner only and does not protect. This is not true. AIO is a great sealant, however, it is often applied incorrectly. The WOWO method does not really give AIO time to bond, so most of the sealant gets wiped away.
When you use AIO by PC, allowing the AIO to buff off allows the cleaners to get their job done, the fine polish to remove light swirls and fine marring, and burnishes the sealant to the paint finish for a longer-lasting seal.
If you over apply AIO, it may start to cake up on the pad or even on the finish. Simply wipe the pad off with a cotton towel.
Priming the pad is okay, but don't over do it.
If you practice, you can lay out a 6" to 12" bead of AIO on the paint finish and run your pad up to it slowly with the leading edge lifted to pull in the AIO. With practice you will learn how to do it without splatter. The result will be better product distribution on the pad.
