I believe a hot tank was traditionally filled with a hot mix of a very strong alkali solution. This would attack organic materials, like grease, oil, and paint, but not steel. Unfortunately it DOES attack the "white metals" (aluminum, magnesium, zinc, cadmium) so real hot tanks have fallen from favor since the days when all "real" engine parts were made of cast iron. I don't even think my shop has a "hot tank." They have a "spray washer" that is just a giant dishwasher that works with warm parts solvent, and they have an oven that they can put an iron block in which will reduce all the oil and paint to ash. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
