Title and description says it all... looking for light polish/glaze followed by sealant.

 

aio and z2 are often used for the same purpose-

and z2 likes to bind to the clear coat...

back in the "old days" david bynon (autopia) was using aio (sometimes with sg) topped by p21s- he became famous for his "perfect shine" with this combo.
i was using "finish first" topped by p21s when zaino came out- then i switched over to zaino/ p21s- sal zaino told me that p21s would not bind to z2, but we found out differently.

if you already have the aio, top it with sg and then p21s, or go straight from aio to p21s.
