Absolutely true, and many "spray foamers" use different spray products, of which come in a assortment of barrels, Light ones, heavy ones, bung type as mentioned and some with banded lids.
Note: these with banded lids, if your going for a double stack (2 barrels) if you reverse the bottom barrel, so the bottom is UP and then put on top barrel so the band is in the middle, they often match up nicely. NO extra work. (other than cutting out the bottom of the bottom barrel)
My cost here is $5.00 for a heavy one, with or without bands.
Also note, the bung type, the lid is crimped on, so you can just grind the center of the crimp, and then nock off with a 2# hammer. The metal will change color just as you grind through (not very thick) I am not talking cutting, which can leave a sharp edge. as well as the crimped edge in tack.
Best of success
