I am fairly devoted the the p21S product line. It's always worked well for me. I've recently considered trying Zaino - and am interested in your experiences.

 

It is a hobby of mine trying different car care products and I have just about every one of them. Believe it or not P21 is one of the few I have not tried, that said I have tried many similar nuba products like Zymol, Swissvax, Victoria, Pinnacle etc etc etc... and have to say that Zaino is the best of both worlds. It has very similar look as the expensive nuba's but yet it is very easy to use and MUCH more durable. It is also very reasonable in comparison. Give it a try and I bet you will never look back. JMHO
