I find Zaino very exciting. Trying different combination of completely compatible products. Do I need to Z2 or Z5? Should i use a mixed coat of Z2/Z5? Etc. There are infinite combinations to dive into to achieve the look you desire. As mentioned in my "Hi" thread I finally found the combination to give me the carnuba-like warmth and depth by still maintain the awesome Z gloss on my black finish. Boring No. Ease of experimentation- great. Number of products needed to accomplish goals - minimal.
