Well I barely put any at all. Granted sealant I do apply slightly more pressure than carnauba paste because sealant obviously has the ability to seep into the pad more, where as carnauba seems to "sit on top" of the pad and has less seepage into the pad. I definitely would not just grind the pad into the paint, but just make sure you have adequate product on the pad and use the pressure that gets the best results for you
.
Also, you should try applying carnauba paste literally with your hand sometime. It's quite a fun and safe way to apply.
And your woman will love how soft and not callused as shit your hands are
