Why would somebody buy a gallon of acetone?  Are they making drugs?

Somebody may buy a gallon of acetone for purposes other than making drugs. Acetone is used in a variety of industries and products, including paint and coatings, automotive products, household cleaners, and cosmetics. It can be used to clean and thin materials, evaporate materials, and remove nail polish. It can also be used as an effective, yet inexpensive method of degreasing and preparing surfaces prior to painting. Acetone has also been used as an alternative fuel or blending component in some diesel-powered vehicles.
