Zaino bonds well over many things, long ago, I tried it over LG, wth no issues. Since I have applied Z2 as well as Z2Pro over several different products. One thing I personally have observed is that many products are robust and bond well interchangeably. The nature of the basic chemical is unchanged by the name change as in "brand"name. IMHO, the genetics of these products is similar enough that bonding issues are rather the subjective opinions of the observer. Prepped surfaces: I have used definate oil based products and applied Z2Pro with no problem at all concerning bonding. Durability? Darn, thats beyond what I do...I tend not to leave a product untouched or on the car long enough to observe the issue, and as long as I have the new product (s) flowing my way...I dont plan to. (thinking of obtaining some junk panel to test durability. Hmmmm Collinite...... wonder how that looks on a light color ?? LOL !
A wierd aside: I edited this post and for some reason, the post was duplicated and there were 2 posts instead of just the edit...:nixweiss AND my comments on Z concerning marketing were wiped, I apologize for this screw up.
