Anyone know where I could find the 5 gal jugs Meguiars uses for their Detailers Line? I do mostly rinseless washes so 5 gallons is a good amount to carry around. What I like about those jugs is the screw cap can have a garden hose screwed into it, that makes filling them very easy. Also, with the correct fitting, I can gravity feed water from the 5 gallon jug to a pressure washer to spray out really dirty wheel wells. Thanks.
