This 2 gallon pail is great to have around when you really need it. We've found it to work well when you're mixing up a gallon of our Concrete Rust Remover or if you just need to soak an item in 1 gallon of Evapo-Rust. The extra capacity avoids the almost inevitable spilling if you're trying work with 1 gallon of liquid in a 1 gallon pail.
