most of you probably already know this but i thought i'd post this for new users. i called zaino today to ask about their products (i've read here that they're awesome) and to find out what to do since i already used nufinish on my car when initially purchased. they told me that all i have to do is wash it once with Dawn dishwasing liquid. there's some chemical in the liquid that will break down the nufinish that's been applied. i thought someone else may have use for this information.
