Not to say you have not been before, but maybe biased. Do you really think Ultima is that great or do you just really dislike the press that Zaino gets so you may hype Ultima more? I have used UPGP on 4 cars so far and one of them is my mothers 2001 Chevy Tahoe and Megan and I went over for Sunday dinner and the slickness is gone as is the pop. I am starting to really think that this stuff is crap. And I dont think that any any of the three WOWO products are that great but of the three I think ZCS is the best looking. I cant say shit about durability because I have not had any of them long enough. Im considering returning the Ultima although something tells me gettting money back from db is going to be rather difficult.
