I would not use these Walmart cans.

I purchased TWO last year. The purpose was for extra water storage in the trunk of a sedan.

I noticed BOTH leaked badly at the cap. There is no easy way to tighten the cap to prevent leakage. There is space in my SUV to allow storage in an upright position but for the sedan, it does require that the container be placed sideways. This allowed SIGNIFICANT leakage.
