I use AIO as a final cleanser/gloss enhancer and base for my Zaino polish applications. Works great. I use ZFX enhanced Z2 or Z5 for the initial layer. Zaino works best if Z1 or ZFX is used per manufacturer's instructions. Any deviation (the non use of Z1 or ZFX) outside the box may be successful but would discount any product problems (i.e. decrease durability, slickness and beading) encountered because of such deviation.
