Hello, I am still fairly new at this, and my plan is to wash with Sonus Gloss SHampoo, clay with the Sonus clay bar, SFX-2, SFX-3, then a coat of P21S. Is this a good approach?
If you car has swirls, water spots, etc, I'd recommend using The Sonus SwirlBuster polish vs. the SFX-2 and 3 combo. The reason is that this polish has an acrylic polymer that will offer a nice base coat for the P21S wax.
