I needed some equipment to hold AP33 and Alodine so I had to come up with a device that would hold enough juice to cover the parts. I thought I would make a mini trough and it holds 1 gallon to cover the parts. It is also 5 feet long and it holds most parts. Some can be bent to fit in it. One for toxic and one for the water rinse. These are made of 6" PVC pipe with end caps. Only Lowes carries the 6". Then I put faucets on them to drain the juice. All PVC parts so I don't have a C-reaction if you know what I mean. I made a cradle to hold the pipes level or 1 bubble out.
