I recently dropped the money and bought the kit from Zaino Bros. This stuff came of just as easy as it went on and the shine is like no other polish I have ever seen. It is a proccess to apply due to the multiple layers, I used the Z5 polish, the Z6 detailer, then finished off with the Z2 polish and it was amazing IMHO. My friend uses it on his 94 Impala SS & Vette as well, both are black w/ silver stripes and the look incredible as well. So if you are willing to spend the time, effort, and money, then I would say go with the Zaino.
Zainobros.com is where to get all the stuff. I will take some pics tommorow and post them up here.
