What is that on the picture???????

The product I use to clear coat work is called... "Varathane" "Diamond Coat"

It has a strange separation until well stirred. That is what spilled on the picture. You will notice the milky color and the liquid separated. That's what happens when it is not mixed well prior to application. I sure hope I can fix the book mark. I was planning on using it for a book I picked up.
