I have been using Zaino for a couple years now and I have found it to be the best on the market. A buddy of mine (Also an avid Zaino nut) mentioned that he found what seemed to be a similar alternative to Zaino called "Finish First". He calls it "Poor Man's Zaino"...Although I don't think its really all that cheap but a bit cheaper then Zaino. The main advantage I see is that you don't have to buy nearly as many products to acheive the same show car finish...not to mention half the effort.
Anyways, it gives the same if not a bit better shine then Zaino does and it doesn't take nearly as long. It is synthetic polymer based just as zaino is.
My buddy has converted to it and I believe I will give it a try now as well. Its really a nice product and they have an online ordering system too! They offer several different configuration of kits as well as an ala carte menue too choose from.
