yinz guys, coming from the tire industry, we mostly use MURPHYS OIL SOAP. it usually comes a little thick, so you can dilute to make your own concoction. Of course we buy it in 55 gallon drums, your size may vary.lol Jim Weppelman :} Pittsburgh 1963 spyder rag project 1964 a/c monza 1961 lakewood 1962 700 monza wagon(soon)
