Dried Up Inka-Gold?

I picked up a jar of Inka-Gold that I have had a little while.
I was disappointed to find it had dried up. I figured I didn't have anything to lose ...

Inka-Gold is water-based so I added fresh water to the jar.
I poked holes to break it up and get the water dispersed throughout the dried up paint.
I screwed the lid tightly on the jar and let it sit over night.
The next day, the Inka-Gold was nice and creamy again.

Do not leave water sitting on top of the paint or beaded up in the lid. 
Too much moisture can make the product moldy.
