Last time I did the driveway, about 4yrs ago, I used 12 5gal pails from Lowes, now I see the 5 gal pails are 4.75 Gal. Really don't remember what they were last time, 5 or 4.75.

Bought old can at least 5 years ago, it too is 4.75 gallons, checked this AM. I think we just get into the habit of saying 5 gallons because it's in a 5 gallon bucket...
