Can't say for sure as I have not used the Hirsh brand spray can. Plus I wanted the quart can because it's so nice and easy to fill a small bottle for the air brush, hit the entire engine with a fresh coat and bang, it looks brand new! The spray cans that I have used in the past make a mess under the hood and over-spray everywhere! You don't get any of that with an airbrush. You can pinpoint the paint like you are using a magic marker...
