Have been using the same pipe setup for a while now, got the idea from another thread here long ago. Works great , rarely change the evaporust. When really want them to sparkle, use metal polish after, then clear coat with rattle can clear. Almost always replace levelers. And most of the time, use polishing wheel on the leg bolt heads after also soaking them in evaporust.
Also think we should maybe take up a collection to get JR a couple gallons. He has been working wayyyyy too hard removing rust. LOL
