The corrosionX will remain a liquid. If you opened your motor and it is a paste then it is contaminated with water, or you didn’t put enough and it just coated everything and disappeared. Clean it out with rubbing alcohol and fill it with clean corrosionX.
I just opened my VESC box after months and the corrosionX was good as new. I moved my receiver to inside the box with my VESC now that my 120cm antenna finally arrived.
