I'm confused a bit with Z2 and Z3, What do they mean by regular paint? Are they talking about cars with single stage paint or just older vehicles that have no clear coat? Does it really matter if you use Z2 or Z3?
To be completely honest my guess would be theres not much difference in z-2 and z-3 maybe just z-3 has more oils for the SS paint to absorb?? But if you know what kind of paint you have why even bother using z-3 or ves versa... Just stick with what the manu. says.
