This 16oz is a big can of this stuff...so if you don't need a large amount buy the small can. The 16 ounce can's brush is significantly bigger than the the normal small cans you get at the Orange and Blue stores. The product works great-just be aware of what pipe size you are working with. For my 2" pvc job this brush was a bit big... Not Oatey's fault-they sell it like this intentionally for the big pipes. I just messed up on my order.
