I read through their web site. They are somewhat secretive of the formulation - the MSDS doesn't really tell you what it's made of. All I can gather is that it's made of wool wax (lanolin).
The Texaco rustproofing I keep touting on this site is made of wool grease. I believe it's the same thing. I have a lot of experience with this product. It's wonderful. I've been taught to mix mineral spirits (not oil) with the rustproofing to make it sprayable. Once applied, the mineral spirits evaporate from the coating.
The web site says you can thin the compound with oil to the consistency you want, but then tell you to use pressure (60-80 psi) to get it to spray. I use 40 psi with my compound thinned with mineral spirits. I'm afraid the oil may permanently change the compound viscosity, and cause it to run and thin out. You basically want the compound to remain as viscous as possible in final coating form.
