The Sentra's have a basecoat/clearcoat paint.
All the info you need is at their website.
Personally, I did:
Z1 - Prep finish
Z5 - Removes swirl marks
Z2 - Finish polish
I try to use Z6 everynow and then, but it's been wayyyy to cold and my apartment garages aren't heated, nor do they have electricity.
I also use their glass polish, but need to find something else now that my windows are tinted.
They pretty much have anything for any part of your car.
