I just leave mine in the five gallon bucket. When I need some plastisol, I mix it with a paint mixer and a cordless drill while being sure to scrape the bottom good. I then get the amount that I need with a measuring cup. I originally transferred the 5 gallon bucket to gallon jugs but found out quickly that breaking up hard packed material in the bottom of a gallon jug through a 1 inch opening wasn't much fun. I cut the tops off of the jugs, stirred the packed material back into suspension and poured them all back into the 5 gallon bucket. Not a ounce of trouble since.
