Yes, if you have any surface pollutants (you can feel them with your fingertips) use a clay bar first.
I use an radom orbitatal buffer for the first two applications (ie the Sonus and the All in One). The sealant simplies goes on with a small waxing pad.
I use microfiber towels to buff.
Tip--To remove sealent, you some detailer spritz to help you remove the sealant.
Finish off with large wool buffing pad to make the shine blind you!
Good luck!
