Does Zaino Z2 Pro spoil or separate?

[imported_gungriffin]

I have some Zaino Z2 Pro and I guess that I must have dropped the bottle because when I went to use it today it was about half empty and had leaked out. It was basicly full the last time I used it about a year ago and forgot that I had it. Could it have separated and leaked out different amounts of different ingredients in it?



Do you figure that the Z2 is still good to use or would it be better to buy new? Also is Z2 about the same as OptiSeal and would it be worth it to layer them?



Thanks in advance- Ryan
